Aside from exchanges, is there a place where people list private token sales.
I am looking to acquire tokens that have little to no volume and have fallen 95-98% since ICO.
You are looking to by useless tokens for what? Any project that loses that much value means they aren't good, what do you tend to do with them? If you are looking for shit coins to buy please kindly go to p2pb2b exchange, exmarket, etc
maybe he will review the worthless coin and examine it, so that he can understand that in the future unsold coins will increase or disappear over time, well doing this doesn't have to buy coins right, after knowing the price is low maybe he will look for information about the coin and if it is possible that later it will go up then dare to buy, and if it is not according to desire maybe not too regret it because it is cheap, I think so
He's just risking in returned of possibilities that the team behind will come back and make things profitable for him, that's why OP is asking for someone who really bought the coin from the ico since the chance that those people who did that able to manage to review the project before they really purchased the coins.
Though this action is really risky as most of the time those developers who their project are no longer visible or already in another projects.
