Cobinhood used to be a good exchange last year as they had huge differences for arbitrage. At some point they started removing pretty much all tokens and exchanges like Bibox and Bitforex got new traction due to them.
At some point they had hardly any market pairs so pretty much almost everyone quit using them.
They came with IEO/ICO - Dexon where they got 3 millions USD. Today after tokens were unlocked came insta dump of the token and their native exchange token - COB.
Now nobody can login to exchange (2FA is not coming) and they filled for liquidation.
