I hold 70% of BTC and ETH while 30% of the leftover are altcoins. Yep, ETH to me is not in the altcoins category. 30% of altcoins usually have a shitload of trash coin in it but I long time hodl of ChainLink and Wave.
I think 30% is too much for altcoin at this stage. You should focus more on Bitcoin and ETH because their current prices are too low and you should buy as much as possible. Altcoins are hard to grow at this stage because because bitcoin and the market keep crashing, you could lose more if you invest in altcoins.
