I usually found people who holds huge amount of shitcoin in telegram more specifically ico group but there's kind of shady, if you want to make a transaction escrow is highly advised but i'd prefer to avoid these anonymous people.
Sounds stupid honestly but still makes sense a bit, you wi be paying pennies for huge amount of coins, since the money you will spend on the shit coins cos they are shitcoins will be penny then it's worth the risk, I knew someone who buy 20$ of WPP and it worths 2200$ weeks ago, amazing isn't it? Since you know what you getting into it's good for you.
basically high risk high return investment but if he knows what he's doing, well it's certainly up to him.
