Will you add support for other cryptocurrencies?
Nope. But for an important reason: we don’t think any other cryptocurrencies are well-suited for protecting wealth long-term. None of them offer the supply-side assurances that you get by holding bitcoin, with its limited and truly unchangeable supply of 21 million.
