You said 'this time...' already a few times!
Don't get me wrong but, everyone has a different risk aversion and what works for me doesn't necessarily have to work for you.
You're more used than me to hold 'blue chips' like BTC, ETH or BNB while I avoid it at all costs if it isn't strictly necessary. Me, on the other hand, I feel absolutely nothing seeing one of my alts falling a ~20% or so.
2018 and holding ELastos from 50$ down to 3$ made me invincible, though.
Pro tip: be a bit more greedy with alts ;)
