The regret I have about Bitcoin is that it wasn't as popular as this, if not, I don't think I would have missed out on being a millionaire in the USD through it.
The problem with the fact that many people who are interested in Bitcoin now are still not millionaires is not that Bitcoin was not that popular before. But in the fact that they did not risk being pioneers. Or did not have enough knowledge at that time. In ether way it is not Bitcoin to be blamed by not being so popular and accessible. It is easy to be involved in something when the conditions are already so developed. But it is difficult when everything is just beginning.
Absolutely true, there are many people who knew about Bitcoin in the past but they didn't get rich and their lives didn't change. Perhaps their lack of knowledge was the main reason for this misfortune. There are many people collect bitcoins from that time but they couldn't hold it until the right time. However, they did not succeed. But Bitcoin is still a great tool to fulfill those people's dreams. If they learn from the past and use the present time to hold on until their dreams come true, I am sure they can change their lives through Bitcoin.
