So in a different way but everyone has a big target in bitcoin, which is to save it and have a lot of Bitcoin in their wallet. Regardless of the accumulation method, it is still one direction, namely holding it for a long time.
Exactly, that's what we're all aiming for Bitcoin. We want to have more BTCs during the bull run and have it sold, not all of it at a better price.
Selling all isn't a wise decision because in the next years to come, the price of it will be higher.
As for fees, it's not a problem, but as you said, sometimes it's really annoying.
The fees are only becoming a problem when the network is being spammed. But so far, there's no signs of it and hopefully they won't appear anytime soon.
