Gbyte reached an important price in July 2017. From that moment that coin was neglected by everybody and the exchanges sold the coin mercilessly. Probabily too many airdrop and too many coin in the wrong hands (exchanges). Since november 2017 something has changed, the airdrops are almost finished, one of the last will occur next march 2018 and the coin is starting to be adopted by many people.
Bittrex will wholeheartedly regret their dumping when GBYTE rises to the $n0,000s. They will go bankrupt because their liability in GBYTE from the airdrops they stole from users is that large.
