No, it is not that easy the way you think! Bittrex is one of the most reputed exchange, it's rank was in top five! Though Bittrex lost its previous popularity but still people trust this exchange than any other exchange. Bittrex will add potential new tokens, not every shitcoin. They will ask your KYC, team's goal, video KYC, and many documents. So, it is not easy to get listed there.
Yes, the bittrex exchange used to be like binance now, but since they didn’t introduce any updates or clean the listing from garbage, they lost popularity, I also really didn’t like the fact that they started asking users for information about where they got certain amounts of btc . I am for anonymity.
