It's prolly safe to say you're somewhat new to the network and maybe you have not experienced a bear market or a period of correction, this is the period most newcomers tend to panic and sell off their stash, but there is actually nothing unusual or strange about the network atm, it is just a period were the market plunges and it happens every now and then in the crypto market.

Having said that, if you're hodling a good coin like Bitcoin, then you should hold your funds for this correction period as it will definitely appreciate back up again, but if the coins in your wallets are pump and dump altcoins that are more or less short term projects, then you can take your returns cause most times when some shitcoins dump, that can be the end of project.
