Many, many people are complaining about BTC withdrawals on Twitter. This has been a recurring problem and support refuses to assist, other than saying to "keep trying" or "buy another coin and withdraw that." Unfortunately, if you have more than a few BTC on the site, it's almost impossible to buy another coin without massive slippage. There's just very little liquidity on most coins so you have to eat a large penalty to get your funds off the site.
If you've been around Bitcoin for a while, you are sensitive to red flags, and this is a huge one. Tread carefully.
This exchange has been so dysfunctional that I'm surprised it still has ANY liquidity. Then again, people stayed with Gox right till the end.
Just a few more red flags:
- coin balances don't match up: if you try to sell your whole balance of a coin you might get a message stating that you have insufficient balance.
- (possibly related to the above) even though I always sell off full balances, I ended up with remainders like 0.00000004 etc.
- coin balances have to be refreshed manually by clicking a button.
- order matching: only exact matches are filled, you can't create a "limit" order like on any other exchange.
- the whole exchange or individual markets go down seemingly daily for all sorts of random reasons, e.g. "to catch up", "to download blockchain", "for upgrades", "for wallet update" etc.
- when it's not down it's slow and clunky to use, PHP and poor UI design doesn't help here.
- keeps adding new coins instead of making it work properly with existing ones.
