If the 2017 experience is any example, they're going to start powering higher (regardless of whether BTC moves higher, goes sideways, or corrects lower). The only caveat I'd add now is that it might not be as generalized as in 2017 - we've had three years to see where the garbage is, and now we might see things limited to just the quality Alts. That would also go hand-in-hand with Evolutionary Darwinism too. 🙂
