If this is really true, it's really good to invest now and wait for the next bull run, it would be more worthy if we invest more compared before. The prediction is a really big amount of money and it would give more profit if things would happen according to the predictions.
It’s funny to me that everyone is waiting for some perfect moment to invest, and there were so many opportunities during 2018 when the price was only $3000, or recently when we had more than a 50% drop. I know most just want a quick profit, but then be careful not to let the 2017 scenario happen to you - many were convinced they should buy, when the smart ones were actually selling.
Most people do not really know how to invest and have never read a whole book about the subject, I know it is kind of disappointing but it is the truth, most people want to obtain profits but they want to do it while never losing money themselves and that is simply not possible, and if that was not enough many want to obtain significant profits without investing a decent amount of capital which is why you see people wanting to obtain 100x profits as ridiculous as it may sound, this market offers a lot of opportunities to make money and we do not really need for the price to skyrocket as much to obtain them but it requires discipline, something that most traders do not have.
