Cryptocurrency is not a gimmick, but *investing* in cryptocurrency is. Cryptocurrency was designed to be used, for trade and remittance, and since its inception it's barely been used for anything but investment.

As soon as it becomes an accepted form of currency - not by governments, but by ordinary people - then it becomes a game-changer and full of real benefits, such as helping the unbanked participate economically and enabling unregulated and cheap foreign transactions.

Elites might "own" a lot of bitcoin, but they can't "control" anything on the blockchain. And holding billionaires accountable for paying taxes? That's got nothing to do with crypto. If anything, crypto would force us to evolve our current paradigm of tax collection: to what is anyone's guess, but looking at our collective history it certainly won't be worse than the ridiculous schemes and loopholes we currently have in place.
