I think It depends if you invested for long term or short term. As a long term investment i would keep it and forget about day to day market prices.

If you invested as a way of earning short term profit then this is very different situation. Currently it is not wise to buy/sell cryptocurrencies as short term investment unless you are experienced in trading and understand the market.

Anyway, crypto is actually the future, so if you want to become financial independent in the future, you should invest in this. If you are not knowing what to invest in, you could try #metashiba, this is a crypto that my friends in the crypto group have been talking it a lot.
