At the beginning I made the mistake, that I bought NEO from Bittrex and hold it there.

Why mistake?

Many of you guys should now, that NEO is generating GAS. So while you are holding your NEO, you get GAS.

Unfortunately Bittrex is not giving you the GAS you deserve... They are keeping it for themself.

The exchange Binance however is giving you the GAS you deserve. So if you want to keep your NEO in exchanges, then binance is the right exchange for you.
