Best decision for me now is to hold it first and eventually when the price rise again, sell it at the best price.
That's the right decision you've ever made for your bitcoin, day trade is profitable but it has high risk than Holding your coins, where monitoring is necessary unlike in holding risk is very minimal.
I personally think that it depends also in what coin you're holding if its for long term or just a day trading.There are coins that are more profitable in long term like just watch the market and let it sleep in your wallet and go back after some years. And some are day trading like you need to closely track and the coin is hype or active in the market.
