As long as you know your money is safe in bitcoin or bank and you will notice the big difference of that two, bank is 100% safe your money while in bitcoin 99% your money at risk but it would be gives you big income in times that the price of bitcoin would go high.
That is right. I think it is better to understand the risk and invest in the bitcoin and keep the bitcoin to yourself, you will be rich.
That's a risk in investments dude when you put your money on an investment like bitcoin. you should be ready with all the possible risks that will happen, but do not worry bitcoin has a great potential in the future so even if you just hold bitcoin wallet, you can probably get a big profit because prices will be higher in the future
