I do not understand why new projects place their coins on shitty exchanges. Even if they do not have the money to place their coins on normal exchanges, it is better then to use the most popular decentralized exchanges.
That's correct, decentralized exchange has a good reputation than some small centralized exchange.
Some centralized exchange are accused of wash trading that's why they have a bad reputation, but in decentralized exchange, we cannot do that, it's the real volume that we are seeing coming from a real traders.
There are only few decentralized exchange now compared to centralized exchange but let's hope with Binance DEX, it will be able to lead the DEX market to gain popularity to attract traders. Binance DEX is still new, launched this year but was able to maintain a decent volume of at least $1 million 24 hours trading volume.
