My name is Justin Cooke and I'm one of the partners at the brokerages mentioned in this message. (Empire Flippers)
Just jumping in here, but I just wanted to clarify a few things about buying/selling online businesses.
First - we actually accept payments and can payout sellers in Krypto. It's typically done in BTC or ETH, but we've also paid out in Monero. If it's on the Kraken exchange, we can receive/send, basically.
Next - I think you're in for a bit of a challenge here if you're looking to sell your business. Most people are going to want more than some screenshots to send you 5-figures. One of the benefits of going with a broker is that they have a set/specific process they go through over and over again, have an audience of interested buyers baked in, and offer protections for both the buyer/seller to smoothly transfer the funds/business through escrow. Not providing that may prove a challenge...and risky for any buyers.
Lastly - if we're listing a business on our platform, it's gone through a fairly rigorous vetting process. It's true that it takes a bit longer (2-4 weeks), but it ensures a level of quality our buyers have come to expect. If you absolutely MUST sell the business in 1-2 weeks maximum, this is likely the only way...but your chances are slim, IMO, and you definitely won't receive full value, assuming it's a quality business.
