The main problem is not that exchanges place bad coins on their platforms, but that such coins generally enter the market.
Indeed, without proper funding, the project will not have money even to pay for listing on a bad exchange.
So the culprits of this whole situation are investors who for one reason or another give their money to projects that are subsequently useless for the market.
As a rule, the reason for investing in such projects is financial interest. Look at the list of top coins.
A huge number of mediocre projects received their funding from us. The problem is not in bad projects, but in people who invest in them.
Good point the problem is how investors choose projects and how they deal with their interest, shitcoins still exists since investors still playing with their fate. Gambling with uncertain project and try their luck if the coin that being listed will work for them and bring them benefits. No assurance but they're willing to take the gamble.
They are very valid points of view, although there is something much more internal to see that they continue to list more and more shitcoins, and it is the business model that exists in an Exchange, just imagine that through the Exchange it is well known at what levels are resistances and supports, just having that information is already a great advantage over any trader. In addition, Market Makers packages are very lucrative, only when they meet the quota for shitcoins owners and everyone wins.
