If we hodl and do nothing, no good or service will be created and it will kill Bitcoin, hodling won't magically make it go to the moon.
I disagree, because I don't think most people actually use bitcoin to buy things, i.e., treat it like money--and yet here we are 15 years after its creation and it's value has skyrocketed and it's become about as mainstream as it's going to get. So even if nobody spends it, it can still function as an asset like gold, a stock, or whatever. And if I was back in 2010 looking at bitcoin's price today, I'd say it's already arrived at the moon.
At the same time, I want to admit that it's good that some people hodl because the majority of bitcoins shouldn't end up in the hands of corporations like BlackRock and in the hands of centralized exchanges like Binance.
I guess it was inevitable that BlackRock was going to end up owning some bitcoin, just like they own everything else under the sun. Not that I'm a fan of them, but they're not stupid enough to paint themselves in a corner by buying too much of it (admittedly, I don't know how much they hold at the moment). There's enough to go around without one entity owning so much that liquidity plummets or some such thing; I'd be far more worried if BlackRock started buying mining facilities. Hope that doesn't happen anytime soon.
