See investing is one thing and living in India does offer ways to invest in Bitcoins through coinsecure but it’s price volatility and the way it is rising does ring alarm bells as it can go down by huge margins any time. What kind of an opinion you have on regulation of Bitcoins in India ? What kind of a future you see for Bitcoins in India especially after being a part of the Blockchain Summits?
Researchers have pointed out at a "trend towards centralization". Although bitcoin can be sent directly from user to user, in practice intermediaries are widely used.[31]:220–222 Bitcoin miners join large mining pools to minimize the variance of their income.[31]:215, 219–222[111]:3[112] Because transactions on the network are confirmed by miners, decentralization of the network requires that no single miner or mining pool obtains 51% of the hashing power, which would allow them to double-spend coins, prevent certain transactions from being verified and prevent other miners from earning income.[113] As of 2013 just six mining pools controlled 75% of overall bitcoin hashing power.[113] In 2014 mining pool Ghash.io obtained 51% hashing power which raised significant controversies about the safety of the network. The pool has voluntarily capped their hashing power at 39.99% and requested other pools to act responsibly for the benefit of the whole network.[114]
In Bitcoin terms, simultaneous answers occur frequently, but at the end of the day there can only be one winning answer. When multiple simultaneous answers are presented that are equal to or less than the target number, the Bitcoin network will decide by a simple majority--51%--which miner to honor. Typically, it is the miner who has done the most work, i.e. verifies the most transactions. The losing block then becomes an "orphan block." 
Blockchain is a technology that allows individuals and companies to make instantaneous transactions on a network without any middlemen (like banks). Transactions made on blockchain are completely secure, and, by function of blockchain technology, are kept as a record of what happened. Strong computer codes ensure that no record of a transaction on blockchain can be altered after the fact.
Mining rewards are paid to the miner who discovers a solution to the puzzle first, and the probability that a participant will be the one to discover the solution is equal to the portion of the total mining power on the network. Participants with a small percentage of the mining power stand a very small chance of discovering the next block on their own. For instance, a mining card that one could purchase for a couple thousand dollars would represent less than 0.001% of the network's mining power. With such a small chance at finding the next block, it could be a long time before that miner finds a block, and the difficulty going up makes things even worse. The miner may never recoup their investment. The answer to this problem is mining pools. Mining pools are operated by third parties and coordinate groups of miners. By working together in a pool and sharing the payouts amongst participants, miners can get a steady flow of bitcoin starting the day they activate their miner. Statistics on some of the mining pools can be seen on Blockchain.info.

Several news outlets have asserted that the popularity of bitcoins hinges on the ability to use them to purchase illegal goods.[129][221] Nobel-prize winning economist Joseph Stiglitz says that bitcoin's anonymity encourages money laundering and other crimes, "If you open up a hole like bitcoin, then all the nefarious activity will go through that hole, and no government can allow that." He's also said that if "you regulate it so you couldn't engage in money laundering and all these other [crimes], there will be no demand for Bitcoin. By regulating the abuses, you are going to regulate it out of existence. It exists because of the abuses."[222][223]
Third, and maybe most important, blockchain offers the potential to process transactions considerably faster. Whereas banks are often closed on the weekend, and operate during traditional hours, validation of transactions on a blockchain occur 24 hours a day, seven days a week. Some blockchain developers have suggested that their networks can validate transactions in a few seconds, or perhaps instantly. That would be a big improvement over the current wait time for cross-border payments. 
“As revolutionary as it sounds, Blockchain truly is a mechanism to bring everyone to the highest degree of accountability. No more missed transactions, human or machine errors, or even an exchange that was not done with the consent of the parties involved. Above anything else, the most critical area where Blockchain helps is to guarantee the validity of a transaction by recording it not only on a main register but a connected distributed system of registers, all of which are connected through a secure validation mechanism.” – Ian Khan, TEDx Speaker | Author | Technology Futurist
The only way to defeat these corrupt bastards is not to go along with their game! Start buying gold and silver in any amount, have paper and coin currency in your pocket at all times. Get rid of the credit cards, do business with hard currency and nothing else, don’t get into debt over your head, trade and barter good and services, invest in new gold mine discoveries, be honest with each other, surround yourself with like-minded individuals, protest against your government and its corrupt officials.
Such an attack is extremely difficult to execute for a blockchain of Bitcoin’s scale, as it would require an attacker to gain control of millions of computers. When Bitcoin was first founded in 2009 and its users numbered in the dozens, it would have been easier for an attacker to control a majority of computational power in the network. This defining characteristic of blockchain has been flagged as one weakness for fledgling cryptocurrencies.
Let’s go back to the part where John’s blockchain copy was sent around town. In reality, everybody else wasn’t just adding his new block of data…. They were verifying it. If his transaction had said, “John bought Lemonade from Rishi, $500,” then somebody else would have (automatically!) flagged that transaction. Maybe Rishi isn’t an accredited lemonade salesperson in town, or everybody knows that that price is way too high for a single lemonade. Either way, John’s copy of the blockchain ledger isn’t accepted by everyone, because it doesn’t sync up with the rules of their blockchain network.
Remember in our lemonade example, how people in town knew that Rishi wasn’t allowed to sell lemonade and that $500 was way too expensive for a drink made from lemon juice, sugar, and water? Those sorts of rules were agreed upon beforehand by every node in the network—they’re a defining feature of the network. If they didn’t exist, then anyone could sell lemonade for however much they wanted.
Blockchain is the digital and decentralized ledger that records all transactions. Every time someone buys digital coins on a decentralized exchange, sells coins, transfers coins, or buys a good or service with virtual coins, a ledger records that transaction, often in an encrypted fashion, to protect it from cybercriminals. These transactions are also recorded and processed without a third-party provider, which is usually a bank.

As a merchant one of your main goals is to be able to accept and process payments as quickly and seamlessly as possible so you can make your customers happy and receive payments without any headaches. Bitcoin Cash is the solution, as it has fast and low-cost transactions. As the world goes digital, electronic currencies such as Bitcoin are becoming the go-to method for paying online and in retail shops. Easily accept Bitcoin Cash directly or use third-party providers to accept Bitcoin Cash using their platforms and convert all or part of the sale into local fiat currency.
I have had the experience of playing at Remitato for a few months and Binance for 2 years. I gave you some knowledge about the two decks that I have been playing. But above all, security is still there. I do not want only because of the security of the floor of the player that pours money into the sea. But the mistake made me more knowledge for the next time to choose Binance. The Binance retains its reputation from the beginning to the present, choosing Binance as its brightest choice.
Tokens & Coinbases: For a practical example, let’s see how cryptocurrency (Bitcoin) works with blockchain. When A wants to send money to B, a block is created to represent that transaction. This new change is broadcast to all the peers in the network, and if approved by the peers, the new block is added to the chain, completing the transaction. The popularity and the controversy surrounding Bitcoin skewed the general perception of blockchain as a technology limited to cryptocurrency application.
Then cryptocurrencies came along and turned this traditional source of wealth creation on its head. When 2017 began, the aggregate value of all digital currencies combined equaled just $17.7 billion. However, as recently as this past weekend, the combined market cap of the nearly 1,400 investable cryptocurrencies was almost $836 billion. That better than 4,500% increase in value is something that the stock market would take multiple decades to accomplish.

Now, if there is no central system, how would everyone in the system get to know that a certain transaction has happened? The network follows the gossip protocol. Think of how gossip spreads. Suppose Alice sent 3 ETH to Bob. The nodes nearest to her will get to know of this, and then they will tell the nodes closest to them, and then they will tell their neighbors, and this will keep on spreading out until everyone knows. Nodes are basically your nosy, annoying relatives.

One of the solutions offered by Deloitte is the inclusion of a QR-code in a receipt. The QR-code is set to contain all the relevant information regarding the purchase: item, serial number, date of purchase and so on. With it, the QR-code also holds instructions on how to find a ‘warranty bot’ on Facebook Messenger. The user can then send a picture of the receipt to that bot, the engine unwraps the QR-code and stores all the product information on the Blockchain.
Joining a pool means you can also use cheaper hardware. USB ASIC miners—which plug into any standard USB port—cost as little as $20. "For a few hundred dollars you could make a couple of dollars a day," according to Brice Colbert, a North Carolina-based miner of cryptocurrencies and operator of the site cryptojunky.com. "You're not going to make a lot of money off of it and with low-grade ASICs you could lose money depending on the exchange rate."
Health care providers can leverage blockchain to securely store their patients’ medical records. When a medical record is generated and signed, it can be written into the blockchain, which provides patients with the proof and confidence that the record cannot be changed. These personal health records could be encoded and stored on the blockchain with a private key, so that they are only accessible by certain individuals, thereby ensuring privacy

Some people would say that trading is a form of gambling. While there these two things have something in common, there are also fundamental differences. When you gamble (and assuming that it's a fair game) you have a certain probability of winning and losing. When you trade assets, this gets much more complex. I don't want to go into too much detail here. I just want to outline the concept how you can earn Bitcoins with trading.
The average price of a bitcoin can increase and decrease unpredictably. For example, in one week in November, 2015 Bitcoin went from $318 on a Monday to $492 on a Wednesday, falling back under $400 by Thursday.[14] Do not put too much money into bitcoin, as it's seen as a high-risk asset. Only buy enough bitcoins to make convenient online purchases.[15]
Lightweight clients consult full clients to send and receive transactions without requiring a local copy of the entire blockchain (see simplified payment verification – SPV). This makes lightweight clients much faster to set up and allows them to be used on low-power, low-bandwidth devices such as smartphones. When using a lightweight wallet, however, the user must trust the server to a certain degree, as it can report faulty values back to the user. Lightweight clients follow the longest blockchain and do not ensure it is valid, requiring trust in miners.[96]
