Bitcoin is a virtual currency. (Decentralized money distributed throughout the world). Unlike traditional currencies such as the dollar or the euro, bitcoins are released and managed without any central authority. There is no government, company, or bank in charge of bitcoin. That is, it is more resistant to inflation and corrupt banks. With Bitcoin, you may be the bank
It is not "printed" by any central entity, but is produced (mined) by computers, where the process is somewhat complicated. Used mainly for offline legal transactions in the deep web as it is almost impossible to find the identity of the person who uses it.
RISK
All traditional financial products have strong customer protection. For example, if someone makes a fraudulent transaction with your credit card, the bank in which you have the account takes responsibility, there are laws in place to limit customer losses. Bitcoin does not have such a security net. If your Bitcoins are lost or stolen, there is no mediator for their responsibility.
Bitcoin has gained a loyal pursuit among those engaging in dubious legal activities, such as drug and gambling trade. As technology continues to advance and become more and more known, more and more people wanting to avoid government scrutiny are likely to eventually adopt it. But federal law enforcement agencies may conclude that Bitcoin is a giant money laundering machine and seeks ways to close it.
INVESTING
I think that Bitcoins will continue to be appreciated, but each of us who intends to invest must realize that it is an extremely dangerous proposition. Before you think you will win, you should also think that you will lose most or all of your money. And with every bitcoin sold for $ 2500, there's almost as much chase as there were a few years ago when you could buy a bitcoin for $ 5. So please invest only the money you can afford lost.
