That could be. It’s Gresham’s Law. People spend their worse monies first and hoard their best money. It’s the reason that, if I have both fiat and BTC, I prefer to spend fiat first. You always keep the money that preserves your purchasing power the best.
Or maybe because it's too expensive to use and to make a private transaction.. so they use it like a digital collectible as Saylor suggest
Just zapped you 42 sats. That seemed pretty fast and inexpensive to use. And lightning is fairly private for senders.
