Only if bitcoin decreases too much or alts rise too much when people's interest will transfer towards alts again.
Bitcoin has decreased quite a bit, but it took altcoins down with it, and that while people were strongly of believe that the moment Bitcoin's momentum would weaken, altcoins would boom hard but thus far they haven't.
I haven't seen much of an indication that altcoins are going to explode any time soon---the dumb fomo retail money is what made it pop hard and they are still not willing to come back because they are licking their wounds.
I expect Bitcoin to fall deep under the $8k mark in the coming weeks, which I believe will hurt altcoins too. I would rather wait for an altcoin season as confirmation than to jump in right now and lose more value.
