@OP, I think the easiest way is just to buy their Tokoin directly from the owner then once you have now their coins, it's up to you then when you want to sell it on Kucoin with your preferred price. One time transaction only, and you can save a lot of time and fees. No need to contact every time there is a successful sale.
yeah. this is easiest way. but not the smartest way. buying tokens now and selling them letter would only be a good idea if you are sure the token price will drop. if i am not 100% sure but 80% sure that the token price will drop. these random tokens are not worth to spend money on. I've use do do this type of stretegy once before and got a big lose. whatever OP doing is right.
