NO. Do not allow ONION to be added to YoCrap (Yobit). They will hi-jack the coins and never update the wallet. Yobit is good those for pump and dump coins that never update their wallet but if ONION plans to update the wallet then say far away from Yobit. Since Yobit is the Roach Motel of the Crryto exchanges. 'Coins go in but they do not come out'
If you are looking to have ONION on a real exchange then Cryptopia.co.nz or LiveCoin and then Bittrex. Please no pump and dump exchanges like Yobit since Yobit is "The home of the broken wallets'
But I love bitrex.
Bittrex is a US company. I think you are meaning Bitfinex since they will not be supporting US customers.
Built and operated in the United States, Bittrex is the next generation crypto trading platform created by security professionals. We are crypto-coin enthusiasts bringing more than 50 years of combined security and development experience to the trading community from companies, including Microsoft, Amazon, Qualys, and BlackBerry.
Given the recent security breaches and reliability issues experienced by other markets, we felt the community deserved better. If virtual currencies are to truly take off, trustworthy infrastructure is a prerequisite.
At Bittrex, our mission is to deliver the fastest and most secure trading platform available.
So looking at Yobit top coins by volume all of the wallet are 'broken'/'Maintenance' beside one
