Don't buy farcaster accounts. You might get rugged. 

They were designed to be easy to use in a social app, not to be traded like nfts. Some tradeoffs we made will make it harder to trade them safely. 

For example, someone can set a recovery address, transfer the account to you and reclaim it back a few hours later.

For those looking to buy an early FID this is something that you all should be careful about, FIDs aren't like ENS, they can be re-claimed back by the seller. Also just to offer another perspective, the value of an account comes from it's contents more than it's initiation date.
