Bitcoin mining operations take a lot of effort and power, and the sheer amount of competition makes it difficult for newcomers to enter the race and profit. A new miner would not only need to have the adequate computing power and the knowledge to use it to outcompete the competition but would also need the extensive amount of capital necessary to fund the operations.
When mining began, regular off-the-shelf PCs were fast enough to generate bitcoins. That's the way the system was set up—easier to mine in the beginning, harder to mine as more bitcoins are generated. Over the last few years, miners have had to move on to faster hardware in order to keep generating new bitcoins. Today, application-specific integrated circuits (ASIC) are being used. Programmer language aside, all this means is that the hardware is designed for one specific task—in this case mining.
Government taxes and regulations: Government and local municipalities require you to pay income, sales, payroll, and capital gains taxes on anything that is valuable – and that includes bitcoins. The legal status of Bitcoin varies from country to country, with some still banning its use. Regulations also vary with each state. In fact, as of 2016, New York state is the only state with a bitcoin rule, commonly referred to as a BitLicense.As shown in the Table above, zero is the least with the number 3 being the most reliable for average bitcoin transfers.

An official investigation into bitcoin traders was reported in May 2018. The U.S. Justice Department launched an investigation into possible price manipulation, including the techniques of spoofing and wash trades.

Brett Redfearn, head of the U.S. Securities and Exchange Commission's Division of Trading and Markets, had identified several manipulation techniques of concern in March 2018.
in the early years of the 2oth Century, the Gold Reserve Banks of America and Europe became the property of these greedy Bankers in American and Europe, no longer owned or controlled by the US or any European country, they became the willing puppets of the Oligarch Regime. These Oligarchs did away with “paying gold to the bearer on demand” because it was now their gold! Paper currency isn’t worth anything, even the paper it is printed on, in fact, paper currency has become plastic currency in many different forms like your credit cards!
Bitcoin is a digital asset designed to work in peer-to-peer transactions as a currency. Bitcoins have three qualities useful in a currency, according to The Economist in January 2015: they are "hard to earn, limited in supply and easy to verify". Per some researchers, as of 2015 bitcoin functions more as a payment system than as a currency.
Elections and polls could be greatly improved with smart contracts. There are various apps already in existence, such as Blockchain Voting Machine, Follow My Vote and TIVI. All of them are promising to eliminate fraud, while providing complete transparency to the results and keeping the votes anonymous. However, there is still a long road ahead before decentralized voting is implemented widely.
