With the current nature of the market now, if you are still in Bitcoin then I think that would be the best since your main aim is to increase your Bitcoin holding, but if you are in altcoins already then be sure they are good altcoins because Bitcoin is still in control of the market and altcoins, or rather some altcoins not among top altcoins will be dumping even more. Also, if you are not in good altcoins, then decide what to do in order not to lose entirely, because Bitcoin is still dominating the market in a big way.
Talking about altcoin season, only few altcoins grew with Bitcoin for the past days now, while others didn't find it easy, therefore if altcoin season is to come, Bitcoin dominance needs to come down, but however instead of waiting for that to happen, as no one knows if it will happen, I think it's better being in Bitcoin or top altcoins.
from what i understand he didnt want to invest in btc but he want alts that are paired with btc. why wish for btc to come down ? just to give way for the alts ? but why not wishing to see them both pump . we can do this if people are going to be like op that keeps on investing altcoins .
btc is doing better now and we dont want this moment to be break down or if they cant wait they are always welcome to join btc . itl be more surer that they can earn than waiting for the unknown in altcoins .
