Maybe people close to Bitcoin know it won't be a usable currency, but unless you closely follow bitcoin, it sure seems like it is built to be a usable currency. Even the name implies this relationship, and the idea of a 'wallet' does too. Tesla just recently bought $1.5 billion worth for exchange, no?
Wake up, this question was reasonable in 2010, maybe 2015. :) Today no serious person is still thinking it would be usable :)
