Why does this question keeps arising repeatedly on this board?
When investors are deliberately waiting for altcoin season, obviously this type of question will keep on coming until expectations met.
With my little knowledge, there's not altcoin season that is coming, if we are still in the bull season, every coins that have intentions of pumping will do but if not, nothing. Is there any historic data of past altcoin seasons? If there is, I would love to have a look at it, so that I can understand better.
You just proved it, because a bull run should also trigger an alt season but if there is no alt season yet, then that simply means that there is no bull run too, which can be true because BTC's value haven't reached really high yet. Sure, it broken a new or another ATH but most of it are only just a recovery from our last/previous ATH.
There are alts that have shown an increase but I think this is also not too much and then most alts are still down or stagnant. Anyway, I searched for that " historic data for alt seasons " but unfortunately I can't find any, though I found this alt season index:
