I think probit exchange is not bad for IEO. ProBit Exchange has a good ranking among the many exchanges on list coinmarketcap.com
Don't look at exchanges from CoinMarketCap but look at reality. PROBIT is now ranked 38, while LATOKEN is 41 and P2PB2B is 51
Even bad reputation exchanges can rank in the top 50 coinmarketcap
That is the valid point CMC is not a measure to judge the exchange reputation. If we explore the IEOs section on that exchange it will make surprise you so many useless projects there even most of them have fake teams behind them but they got funded through this platform. I think Binance and Okex are good choices at the moment.
