It is good that Bitcoin's price is so high since many gained many profit from it. But this hype is too much. Bitcoin is so much expensive now and every step we see Bitcoin increase. Well, I say it is time to go down. A price around 3000 USD is reasonable but going beneath that is much preferred.
What would it take to make Bitcoin's value to drop again? A new hard fork? whales dumping coins? anything, I just hope Bitcoin to drop tremendously.
The price of bitcoin will drop naturally. Don't worry about it.
There are always stages of a bubble. Currently we are nearing the top or already at the top, once people realize that this sort of price level is not sustainable in the long run they will start panic selling, and that drives price down.
As long as you don't panic alongside them you should be able to make some nice profits. Usually the sell off is too excessive which leads to the price bottoming out before springing back up again.
