A crucial development will be interfaces—wallets capable of managing many currencies seamlessly. Thanks to innovations like sidechains, decentralized exchanges, and liquidity protocols, converting between different cryptocurrencies will become instantaneous and low-cost. The user experience would be akin to moving between different apps or communication modalities—text, video, or email—via a single unified interface.
This fluidity allows users to express their intent in the most suitable currency for a given transaction, whether paying a large purchase with Bitcoin or tipping in Doge. Over time, this will lead to multi-modal and context-dependent use of currencies.
