There are three ways to trade Bitcoin:
1)-Bitcoin can be traded on specialized exchanges, but these are not supervised or controlled by regulators. In the event of a problem, sudden disappearance of the trading platform or manipulation ... there is absolutely no possibility of recourse. On the other hand, you physically own the Bitcoins (the counterpart is that you will not have to lose your Bitcoins on your USB key or on your PC or else forget your private key because in this case there will be no way to recover his investment, the bitcoins will be permanently lost). You should never leave your Bitcoin on the website (Wallet Web), if it disappears, the Bitcoins will fly away with it. It is therefore necessary to transfer them "physically" systematically.
2)-Regulated brokers offer Bitcoin trading. The advantage is that they are controlled and monitored by regulators thus offering guarantees of reliability and legal protections for consumers in the event of a problem. This is the case for example ProRealTime CFDs with limited risk. We do not physically own Bitcoin but a derivative of Bitcoin (a Bitcoin CFD) which allows you to take advantage of price variations.
3)-The CME has announced the upcoming creation of Bitcoin futures that will be tradable. This will therefore create a third way to trade Bitcoin. We don't have a lot of details at the moment. But this solution passing through the Chicago Mercantile Exchange (the Chicago Stock Exchange) will also be secure and regulated. Here again, we will buy or sell a Bitcoin derivative, we will not own it physically.
