I also agree that the 5 exchanges mentioned in the opening post are really supporting bad projects, and therefore are blacklisted from the list
exchanges that you will use. Especially P2PB2B is very much detrimental to its users, almost 90% coins listed on P2PB2B exchange are shitcoins.
I hope investors are smarter at this time in choosing exchanges for investment.
Most of the coins listed at P2PB2B are shitcoin, and certainly you will not be able to make any investment if you choose to trade here. Currently, if you want to succeed the project, you should choose exchanges such as Okex, Huobi, Gate, Kucoin because these are four high liquidity exchanges, and any IEO makes investors feel satisfied.
