Legitimizing Bitcoin more than offsets the environmental benefits of electric vehicles.
eg. the USA inflation rate is 2%, whereas the interest rate is 0%.
Its inevitable that savings will flow out of fiat and into all kinds of other assets. This is the entire purpose of low interest rates - to inflate the value of assets held by retirees, pensioners, and the ultra-wealthy.
Bitcoin is unique because the supply cannot be expanded (beyond what is scheduled as rewards for miners) - unlike gold, shares, living spaces. Its also significantly more liquid and easier to transact than any of those assets because it is digital and global.
