I am glad that you are working to improve the PHORE marketplace.
Payments in Bitcoin will be very convenient for most sellers and buyers.
Bitcoin blockchain transactions may require a lot of time to confirm
I think it's better to use PHORE or other faster blockchains for payments.
Bitcoin is the past. I advise you to use PHORE BLOCKCHAIN or as an alternative to TRON or Stellar.
Payment in the marketplace should be made only in PHORE coins.
