The very point is that some of these mining coins are looking for ways to siphon money from people. That's why I hardly partake in them because this same act of asking for Ton as a way to be eligible for mined coins
It's clear that many of these projects just want to steal money from their users, instead of having to burden users with 0,5 TON in transaction fees, why don't they follow the path that the big projects do, namely by partnering with an exchange that will list their token, so that later transfers can be done off-chain.
