Also they do mention that they'll add more altcoins after feedback is received from the users. However I'm curious if they plan to add two-way conversions, so we can exchange LTC to BTC for example.
I think i remember OP saying somewhere that the conversions are one way so that the customers can have 100% confident that the LTC they receive are not tinted.
More conversion options would be good thou. Maybe they will keep adding more with time.
