Why are you looking for such coins anyway? If there is no secondary market to sell them then those coins are essentially worthless. If you think that one fine day you will see them listed and their price will be next to bitcoin then you are being fooled. Crypto is such a sector which is worse than the wild west. Here you will see shitcoins everywhere and you cannot trust any project's team members words.

Moreover anyone dealing with the OP please be careful not the send first, but to use an escrow from this list :

It is never a bad/pussymove to use an escrow. Trust only the escrow when dealing with a username on the internet. Send them a PM here first as well to verify that they are same on the site and telegram if you use it to deal with the OP.
