Think of it less as "cashing out" but being liquid into fiat. BQX will always be worth something on the open market, but the liquidity network will allow you to use BQX to make payments in any form of value.
I meant not the BQX tokens but the ability to cash the Fiat from the declared available cryptoers directly, by changing the stock exchange. Is it possible such an option or multi-purse will be used only to store different coins?
