It strikes me that a fundamental problem of bitcoin is that it's a deflationary currency, so there's no sense in spending coins if you can just hold them (other than to exit the volatility of the market), because the coin will likely be way more valuable if you just keep it. Whereas with traditional currency, you have an incentive to spend it, because a dollar today is worth more than it would be a year from now. Am I missing something there?
So it seems like as an actual replacement currency it can't work because buying things with it is a bad idea. Is solana different in this regard? It seems with other coins the value is in sending and receiving money based on real currency? Except that transaction happens somewhat publicly if you're not funneling different amounts through different wallets? I'm not trying to be glib, but I feel stumped on what I'd use cryptocurrency for other than a long hold investment or to buy something illegal. I know that's a common complaint, what I'm hoping for is someone to tell me where I am mistaken?
