Yes, there will be millions of such people. Crypto currency is a very promising and very affordable way of investing. And most people will miss this opportunity.
I agree with you many people are relying on price increases, but we can not do it because of loss money and they wait for the right time to invest it again if the market will rise, what we gonna do for now is to be patience.
They will regret things that they didn't bother to investigate and study, crypto market gives them opportunities to join the ride while its still on the process of progressing and conquering the digital world, using another way for faster transactions, many millionaires will adopt this when see the positive side of this system, the industry still young and things still good for joining so instead of thinking those regrets better to encourage them to study and learned the system for their own benefits.
