I think temporary drop, don't panic, be patient.
Bitcoin price will increase soon.
It's time to buy bitcoin.
Yes, that can easily be seen. However, it looks like ETH is on the rise, so it awaits to be seen how things work out. I guess all we can do is wait for how things turn out.
Bottom line, don't sell, especially not to USD or any other fiat currency. The best thing to do is hold or trade. This is not the end of the line for Bitcoin, so I see no reason to sell.
This is one of most reason why people loose in trading because of their uncontrolled emotion. If you are really confident with your bitcoin then don't sell on panic because for sure you will loose. Hodl bitcoin, it will gives you more profit in the future, be more patient.
