I was in altcoins for a couple weeks after bitcoin started rallying and after losing about 30% worth in sats I sold and got in bitcoin.
My thought was this - if bitcoin is pumping this hard and alts are 70% behind it why are the whales not buying them? When btc goes up alts go down, when btc goes down alts go down even more.
I think the whales that are pumping bitcoin will get in after the btc corrects. I think that will be the point of maximum profitability. If Bitcoin will correct $1000 let's say from 7.3k to 6.3k that would potentially smash the alts to another -30%
The last 2 days alts started to keep up with BTC so I initially thought that tides start changing for them and whales are slowly stacking - but if you look at the charts most alts have dumped again - take eth for example: it went to $203, now it dumped to $193 and it's still dumping while bitcoin is going up.
Like I said, I don't think whales are interesting in buying alts yet, not until the bitcoin correction.
I might be wrong though, so keep that in mind.
