Been here since 2013 and I already saw this happening at least twice (2014, 2018). The price skyrockets, predictions are crazy, companies get in, adoption seems to get boosted, and many other things we are experiencing now. Then, one day the price goes down. From 1200 to 200 (2014), from 20000 to 3900 (2018). I know we all want this time to be different, but I truly think it's going to be the same.
Be Smart. Define points to sell and transform the numbers on your wallet on FIAT. Chances are you will see it crash and go much lower than your exits. If you are a holder, then this will allow you to buy cheaper.
Those are my two cents ...
Well, companies have never gotten in before (other than the odd company deciding to be the lone wolf and jumping in). That's the difference. If the companies end up panic selling everything no different than FOMOing retail investors then it will end up being the same. But there is certainly reason to think that companies and those in charge of investment firms have more experience than the average person who heard about some investment making people rich and jumps in trying to get rich quick. Institutions are much more likely to buy for the long term. Maybe we will get another year long 80% drop later on when this bull run ends, but it might also be completely different because a different breed of investor is driving this bull run. Sure price is skyrocketing and there are plenty of predictions, but the ones doing the buying are different.
That said, of course being smart, figuring out exit points you'll be happy with, and planning to re-enter as well is all good, though take into account the fact that if you plan to re-enter 80% down or something you may end up re-entering at a higher price than you exited because the market is changing now. Best not to exit entirely, but just exit partially when you are happy taking money completely out of Bitcoin.
