Hi Mark,
You could post that you have an account for sale on the Bitfinex reddit: https://www.reddit.com/r/bitfinex/
Or possibly even Craig's list. Or post on Steemit - you could sell for steem or SBD also.
I would however HIGHLY recommend getting an account with Kucoin - If you buy and hold 1 or more Kucoin they will GIVE you alt coins!! Truly ... so grab an account with my referral link and enjoy the free crypto!! : Kucoin exchange - Use this Invitation code: 7dPeh1
