Keep holding. My suggestion is to even buy if you see the chance to if bitcoin drops to under $7000 at any stage this month for whatever reason. I personally think that this is going to be highly unlikely to happen, though.

But if you do have BTC, keep holding it until AT LEAST $8500 before you take your profits.

And when you do take your profits i would suggest buying at a lower level once the price retraces, and continue to hold.
