Bitcoin may be useful like Gold is useful, but it's the other chains like Ethereum and NEAR that provide tremendous value. The velocity of money on NEAR (and its closest competitors I'm sure, but I don't know enough about those) is so fast and I am able to conduct business with people across the world orders of magnitude faster than was previously possible. Banks will never catch up. Crypto still has some kinks to work out, particularly for less tech savvy users, but the fundamentals are so so much better than the existing banking networks. Try doing international business at 5am on a Sunday with a bank.
