Congrats for given this a go, good job. The only hesitation is of course is payroll tax reporting. This is something you must be able to do for an employer or really your service is of little value, due to assessed penalties of non and/or late filings. I would suggest taking one State at time such as CA, as soon, it appears cryptos will be legal tender and figure out how to do all necessary payroll activities, such as tax reporting to State/Feds, wage garnishment, etc., once you have this, then you've got something. I wish you good luck in your endeavors!
