I have dozens of shitcoins that cost around $ 30 -100 $, but as a rule, they are all on the Ethereum network, and selling them on Uniswap means losing 20% -30%.
Moreover, such small amounts will not solve anything. I think I'll wait until something of this shit grows.
Sorry, but I will say that your tactics is bad. If you can sell your shitcoins with a 20-30% loss, I would suggest do it and hold Ethereum instead, or exchange them to other, more reliable altcoin. As they are shitcoins, their value can drop to zero anytime. Basically, holding them is identical to loosing.
You wait and hope their value will grow, but what if this never happens? Or as a shicoin, their value might grow only with a pump&dump. And that is quite a fast process. You will just blink, and pumped price will start to fall down. You wont have even time to transfer them.
