Back in the day I used to hold dozens of coins. But the reality is that if you have a few concentrated coins with good conviction, you're generally better off. Especially this cycle. In previous cycles you could get away with the "spray and pray" strategy as everything would eventually pump anyways. That's not the case anymore this cycle. My main exposure remains in BTC, ETH and outside of that I rotate in and out of some mid/long term holds as we go.
