I kinda have also come to your conclusion.
Have like 4 Altcoins I'm hodl'ing because well, hoping for a pump and not underwater yet.
The only one I do have a bit of faith out of the above 4 is Litecoin and that is simply for Mimblewimble.
But at this rate, I'll have cashed out the remaining above at HOPEFULLY the next pump and be all in for BTC.
It is obvious that where BTC goes all the altcoins follow anyway, just have to pare this down from these last 4 altcoins hoards of any note.
I did have a dozen altcoins hodl's at one time...so it is progress.
later
