Cobinhood team is very serious (Telegram https://t.me/cobinhood), if there are any delays in withdrawing Ethers it is because the Ethereum network is currently very congested. Furthermore they can have 0 transactions fees because they knew from the beginning that COB would go to the moon, plus they offer the possibility to trade with up to 10x leverage, taking small interests. Many coins will be added next week, this exchange has the potential to quickly become bigger than Binance. Buy COB now or cry later.....
