Hi @bayuya, when I said 'sales', I was referring to something like '10% off', '20% off', etc., rather than talking about sales as in 'a record of a sold item'. What I mean is that they wouldn't have to show what amount was paid if it was paid in a traceless crypto, which would make taxation/persecution more difficult because it would be tougher to figure out the profit that would be taxed. :)
