The 50/50 split I use for my crypto portfolio at this stage in the cycle:

50% in long-term investments: Think $BTC, $ETH, $SOL, $HYPE etc. Will still look to TP a decent % on these as prices head into mania territory, but with the idea of being exposed longer term (multi-year).

50% in short-mid term swing investments: Mainly altcoins that are narratively aligned with the market, and are exhibiting relative strength, + some low-cap punts that could pay off in the right environment. I'm much more "ruthless" with this section of my portfolio (i.e., cutting on weakness, tweaking portfolio based on opportunity cost), as I'm under no illusions that most of these coins will go to 0 and never come back. That's my base case at least, if I'm proven wrong - great. Sometimes I'm heavier in cash with this portion of my portfolio, sometimes I'm more heavily invested - it depends on where we are in the cycle.

Bonus: You can also have "sub weightings" for a position. Take BTC for example: You could have 50% that you hold long term, and 50% in your short-term to mid-term portfolio that you swing trade based on strength. The key is making this dissection very clear in your portfolio - I recommend using separate wallets/coin trackers for both: tagged "short term" and "long term".

Most people f*ck up because they mix and mash all their holdings in one, without a clear plan for each holding.

(excluding stablecoin weighting - which oscillates between 30-50% depending on if I have active trades open)
