hello friends
bitcoin is like any forex. only trade if you have experience trading bitcoin or other fx. you can win big but also lose big.
if you've no experience trading fx, follow the advice in the mainstream media and just invest a tiny amount of your personal wealth (like 2-3% i think is the official advice). do not take any leverage. buy and hold. only put a very small amount of your money into it.
if you ignore this advice then you will find out eventually after much hard experience that it is in fact right
