For my crypto, I maintain an allocation of 45% BTC, 35% ETH, and 20% alts.

Although I have some alts that I hold long-term, I trade most of this stack.

I periodically rebalance to maintain this allocation.

It's worked well!  Sold ETH to buy BTC a few weeks ago (at ETH/BTC=0.054), and bought some ETH back yesterday (at ETH/BTC = 0.0295).
