I am wondering, what's the point to regret ; if I did invest on bitcoin in the first place??
But, I get it now, yes, it's not so important but could influence people's minds to think what if I invest right now, and I could be a millionaire maybe someday in the future, maybe it takes 10-20 years but it's worth I guess.
The point is, to believe in bitcoin as it has been proven all this time to achieve unbelievable value and its potential still waiting to be revealed. It's not too late, as we're still in the early phase of bitcoin development and there are many countries will regulate or support bitcoin economics in the next few years for sure.
