If someone bought $100 of Bitcoin in 2010 and kept it until now, they would now have around $6 million.
Do you think the same could happen again in the next 7 years? If I now own $500 in Bitcoin could that be worth $1 million+ in the next 7 years? Or is it extremely unlikely for this increase to happen a second time?
It is very possible that your $500 worth of bitcoin could double and even 10th times its value. It is very possible because bitcoin price really gives income and its price always increases. But as to the issue that it could worth a million is more of impossible. I am not being negative, it is just too much. But who knows, we cannot predict about it.
