What is your preferred method of payment? Seems, you are interested in accepting some of your preferred altcoin, that's why you have posted this thread here?
I think you must state your preferred coins in which you want to get paid. If you are in confusion on which coin you may go then I suggest you to accept Ethereum or Lisk or Waves. Other coins are not stable that much.
You may post in
digital good section if you want bitcoin payments.
