I think Hitbtc plays a lot with the market in its favor. If we see how many coins created in less than 1 month are put on the market at incredibly low prices, after the price is inflated, they close the wallets so that no one can withdraw or deposit. The case of the SBD that in HIBTC has a value of 21 $ but it is impossible to deposit or withdraw SBD. Everything is part of their strategy to show in Coinmarkecap higher prices than the competition to get a better position in the TOP 10.
