The way I read the ann tonight was we will not be able to sell for $20 for 30 days after you become a member of paybase. You have to be tier 4 to sell to fiat.
Then sell for btc and make btc>fiat on coinbase or any other exchange
Tier 1
May purchase XPY with BTC
May send / withdraw XPY to wallets
May apply for Tier 2 verification.
Tier 2
Verify a credit card or bank account
Purchase up to $10,000 of XPY with FIAT
Purchase up to $500 of BTC with XPY
Better off keeping XPY out of PayBase and gambling on a similar price appearing across all exchanges.
