I think there are multiple angles to look at it from. If you are confident that cryptos won't entirely go bust and will gain more global adoption, then it pays to keep buying what I like to think are the 'key' coins that you believe would stand the test of time. Personally, I'm simply locking in positions for the next bull run. The rule is simple, if you can 'afford' to spare the cash to buy cryptos without affecting your daily life, then these bear market prices are a steal...that's how I see it
