Well it's true Bitcoin has the potential to reach $1M from this point. That's means it's solid 10x. If any digital currency would survive it would be only Bitcoin. Also exactly this was happened last beae cycle. I saw lots of people were happy that they didn't bought Bitcoin at high. They are now crying like this. We would never know when is the right time. It's now or never.
Those who cry that Bitcoin prices have skyrocketed to where they were expecting them to reach before and did not buy when they saw them on the lower side will continue to complain, as that has been part of them now; they don't want to buy, they just procrastinate until prices pass that level. Waiting for Bitcoin to reach an X amount before purchase does not do anyone any good, as you can't always predict market movement.
