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.
lost BTC with this fellow, and a lot of money! Venmo closed my account because they couldn't credit the money he sent! Scammer! The thing is I did a past trade with him and it cleared but this time he decided to scam me.
