While I think HODLING is a valid long term strategy I think that people should at least consider the following stock market sayings
1/ The trend is your friend
2/ Run winners and cut losses
3/ No one ever went broke taking a profit.
If you got into BTC way back when then this bear market is probably insignificant in the grand scheme of things and you can HODL it out. If you got in during December 2017 I am not sure this is the case.
Given what is currently going down it might be an idea to consider realising some profit /losses, trim back exposure to cryptos, and wait for the next crypto uptrend.
