Do people buy real world things with cryptocurrency now? Is this even a requirement? People aren't buying anything with GameStop stock, but it seems to be doing fine.
Owning a cryptocurrency means nothing if you can't actually use it as a currency in real world.
GameStop won't keep increasing for ten years, like crypto did, without some real world fundamentals.
Even in GME case, you have the short sellers as a backbone for its rise, not just buying and selling for the sake of it. Without the short sellers, GME wouldn't have risen up that much.
Any decent one is using Monero, which isn't necessarily the target of a ton of speculation, I think.
Disclosure: my sell orders are always higher than the current market rate
