Pay with BCH without being taxed

France and Belgium taxes to 30% benefit if BCH is converted to fiat with benefit So if we don't convert bch BTC etc to fiat no benefit no taxes... Purse.io let us pay in BCH for buying Amazon product But not for France ( i tried but even with 20$) nobody take my order...=( *Convert bch to gift card=converted in fiat so no way...cause i will have to declare benefit and pay taxes *Credit card for paying from crypto same issue Is somebody have an idea to buy on Ebay Coolblue etc as www.purse.io but for France and Belgium ? Thanks
