Firstly this totally depends on what you're doing. Are you trading or investing. This are two different things and the approach can be different. If you're investing for long term then ignoring the market until your target is reached would be the right approach in this instance. You might get tempted to take profit along the way but sticking to your investment plans would be the right thing to do and this will help your devolvement as a professional investors.

While in trading, understandably, people trade anything including shitcoin in hopes for outsmarting the market or riding the hype to get some profit. In situations like this, you're to seized every opportunity you see and take profit, I won't advice existing the market totally but your capital has to be secured then you can consider adding some profit and extra cash for buy backs Incase you still believe in the project.
