Already twitted wavesplatform but for discussion will add it here as well>
We need cheap (with less than 1% commission rate or even at the price of ie SEPA transaction) deposit option of fiat. Ie USD as wUSD, EUR as wEUR, RUB as wRUB and etc. With that we would achieve a working DEX market where waves and other stuff could be traded directly for fiat assets. As long as it could be done via direct interaction from the banks meaning that KYL/AML are in some sort automatically filled.
Later on withdrawal of fiat is also need. That part of course would require a decent method to authorize a person, but if it would be on same level as centralized exchange's withdrawal options with very low fees then why we would need centralized exchanges at all? Maybe only for additional market capabilities (ie arbitrage) but if centralized exchanges won't be providing a way of fast transactions then with coming of atomic swaps different DEX platform would benefit and we definitely would see and income of transactions. Or maybe centralized exchanges how is already supporting Waves as trading asset would support also movement of funds in Waves assets? What you think about that?
