I think Bittrex will only provide support for Bitcoin Gold by crediting all Bitcoin account balances on their exchange. However, they will not support the immediate trading of BTG, so their clients still need to wait until it is live or tradable. Or, if their clients can't wait, they can just transfer it to another exchange with support for it, e.g. YoBit or HitBTC, and sell it for BTC or any other coins of their choice.
Yeah, they made it clear in the statement that they wouldn't be introducing BTG trading. If you thought so it's your mistake. What I'm not clear on is when we'll be credited. It makes me nervous leaving anything on Yobit but so far they've caused me no issue, and what was essentially a frantic seesawing futures market for a few hours made me a killing. Meanwhile, there's no hint of getting a BTG wallet on Bittrex.
I'm not really having a go at Bittrex. Reading it back, their statement doesn't actually say a specific date. Guess I just figured it wouldn't be too long after the snapshot. My mistake. The price is so low now it's not that important anyway.
