Lets give an example for Electronium. They advertised that Electronium is tradable on Altex exchange. They must have enough knowledge to know scam exchanges. Right ?
But when the exchange stopped to work, they told: "Ask the exchange for the money, don't blame us for your exchange choice".
In this case the education will not work. The big currency players have to manage the traders.
here is where the problem becomes more complex, on the one hand we have many shitcoins that are created every day and on the other side we have few high quality exchanges that offer very good services to their clients, and these high quality exchanges do not accept list shitcoins and they charge a lot of money to list any altcoin. So the shitcoins try to list their currencies in the shit exchanges, and the result: people are the ones who lose money. It's important that people get away from shitty projects and get away from shitty exchange.
