From my experience with many previous buyers, it is not a good idea to purchase a Twitter account from a stranger, as the seller may recover it easily through support by providing proof of ownership, even after the buyer changes the account's details. Even the followers of the account may be fake,, and if you audit the rael followers, the number could be very small compared to bot accounts, which may disappear after some time and if the account has low engagement, what's the point of buying it? You wouldn't even be able to use it for bounties or earn money through marketing. What I see is that building a Twitter account from scratch and publishing high-quality content, and targeting the cryptocurrency field with valuable information is a much more effective solution.
