Lemmy being decentralized is a solution to a problem that exists: media companies start nice and then fuck their users when they have enough of them. Decentralization means that acquiring that much power to rug pull is way harder.

Bitcoin has been forever a solution without a problem. The concept of Bitcoin doesn’t make sense, the execution of it even less. So the only use it has is taking advantage of techbros’ hopium that one day an actual problem will be solved by Bitcoin.
