I've used this exchange, but it's been a long time. Because there are tokens listed on the tokpie exchange. And at that time the new tokpie exchange was launched, so not too many conditions were applied. Maybe for now we need to upgrade, by holding a number of tokpie tokens, depending on the level being upgraded. I haven't used this exchange in a long time, so don't know about the methods they employ. This exchange is less interesting to me.
