Venmo is instantly reverisble much like credit debit. This is one of the most DANGEROUS ways to sell bitcoins and is favoured by scammers. We discourage using Venmo unless it is for very trusted trade partners.
Good buyer. Very fast when he is online. Will update this review when needed if I can.
Update: Anyone interested in this buyer might want to look at this review (not saying he has any problem, but if this message disappears...)
