You're too late to sell because the market is dumping already but I'm sure you still have profit with your holdings since you bought a year ago when the price of ETH and BTC was still cheap, so the decision is yours to make.
If you are planning to sell, then know your biggest reason why and if you are satisfied with the profit that you have then so be it. Always have your target price to sell so you wont lose the chance to take profit, and have a back-up plan if things didn't go according to your plan.
I don't think that it is too late to sell, as the OP stated that he has bought at a certain price last year so if the price when he bought the bitcoin and the current price is not the same, I think that he still profited from it. Got to agree with you about having a reason to sell because you need some sort of conviction so you won't regret your decision. If there ever is a back up plan for me, I think that selling half is the best one. If you are planning to sell, then know your biggest reason why and if you are satisfied with the profit that you have then so be it. Always have your target price to sell so you wont lose the chance to take profit, and have a back-up plan if things didn't go according to your plan.
