at first i was interested in things related to elon but now i don't really follow and even still not interested about what he does be it positive or negative about btc. because his statement is always changing all the time and can not be trusted completely.
the issue of whether elon and tesla will return to accepting bitcoin after the energy consumption problem is resolved I'm not sure if they will care or not. they seem to care about this but on a closer look I'm not sure about it. because Elon only cares about his world not with btc.
even if renewable energy solves the problem of mining this won't guarantee it will be friendly to btc, but it doesn't matter because elon is there or not I don't really care about that, although indeed with him he can at least have a good influence on btc because influencers like him have a lot of followers.
A business man with the interest of making money in mind will always finds a way to make things beneficial to them, Elon is no difference, his popularity has increase even more since the announcement of Tesla accepting btc, much attention than before, the crypto community is big and he his tapping from it, already he has big support now include the support from crypto lovers, Elon is enjoying the best of both worlds, Tesla and Crypto, he already said if 50% btc are greener his company will consider, I believe he is still looking towards that direction.
