providers were some of the first to hop on the crypto wave. Myself and many of my acquaintances have been accepting crypto for some time now and I can say with deep(throated) appreciation, we thank those clients for it. however, I have met providers who were paid in small gold bullion (sploosh!), given stockpile gift cards to invest in companies of their choice, etc.
Many providers have parameters when it comes to accepting crypto: usually not for the first appointment and typically, more strict remittance of payment standards. As the OP, you know this but others may not: crypto transactions can take anywhere from several minutes to several hours to be confirmed and completed. That said, if anyone is going to pay via crypto, be prepared for deposits and remitting the full rate a few hours or days before the appointment. There is nothing that will pull both parties out of the fantasy faster and bring both smack dab back to earth quite like reminding a client to put the rate down and/or to remit the rate during a date (or worse - as they are getting ready to leave).
unlike cold hard cash, charge back and disputes can and do happen with any and all methods of payment surrounding credit or debit cards. so while being able to successfully accept these payment methods via third party payment platforms is convenient for clients, it can bite a provider in the ass if the third party payment platform notices suspicious activity or if a dishonest client does a chargeback. this is one of the appealing aspects of crypto currency; once the transfer of funds begins, the funds are placed in escrow until the transaction is confirmed by both parties and once complete, it cannot be reversed.
crypto is not going anywhere and at some point, may very well be accepted as a valid form of currency everywhere; however, in this industry cash will always be king but crypto and gold bullion will always be at the round table
