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.
The price surely will be corrected at some point, there are some minor corrections yet the big one seems to have not come up to the surface.
everyone who has sold at $42k maybe obtains a considerable profit right now, but what if bitcoin hits $50k this week? they could have made more profit, you can sell some portion but do not sell all your bitcoin at once, instead set the target at a higher point, probably at $100k during the bull run market or at least until Q4 2020 that the value might hit the peak.
