It works like this basically;
- coin pays the fee to Hitbtc.
- coin has to generate x volume per month or whatever other time frame.
- coins who can't meet the volume requirements are forced to pay a fee to keep their listing, if they refuse payment, gone they are.
I am pretty sure that all the details are communicated as clearly as they can be between the coin and Hitbtc itself. The only point of annoyance is that the users are the real victims here as always. The only way to not get sucked into these practices is to avoid using shitcoins as much as possible.
This is interesting. Seems a pretty smart way of doing business from their side but doesn't seem a good deal for the coins. If they think it for the long term they should eliminate before the listing imho.
