OTC for sure, forget fees if you have the buyers ready, doesn't hurt you to offer to get the bitcoin off the miners without charging fees, since you already will get commissions from the buyers. Sort of like maker no fee kind of deal. Look for those new entrants, old ones probably have longstanding deals they aren't likely to disband. Trust in this business not easily gained.
Trust wont really able to built up overnight but somehow we can manage to make it on gradual.This is business and offering on that way is already worth to try.
I wonder if selling btc p2p is still a great way since you have no fee and you can meet the buyer 1 on 1 without no doubt.
Possible option but somehow risky compared to OTC which others do talk above.
