Anthropic does not accept crypto, so what is this?
Claude Pro and Claude Max are billed by card and through the mobile app stores. There is no Bitcoin or USDT option in Claude's billing settings and none has been announced. What Anthropic does support is gift subscriptions: a purchaser buys a plan and receives a redeemable claude.ai link, which anyone with an eligible account can apply to their own account.
Nothing about that mechanism requires the buyer and the recipient to be the same person, which is what makes this route possible. You pay us in the cryptocurrency of your choice, we buy an official gift through normal channels, and the genuine claude.ai link appears on your private order page. You redeem it yourself, on your own account, in your own name.
