As a bit-z user here's my two cents on it:
- It's easy to use; for newbies like me it makes a huge difference. Thumbs up.
- Their lower withdrawal limits are insane. For example: DOGE. You need at least 10K DOGE in order to withdraw them. Thumbs down.
- Some withdrawal fees are also insane. Seriously, 0.01 ETH? Big thumbs down.
- Sometimes their servers got the hiccups, like today morning. Shit happens to everyone, so thumbs neutral.
This exchange, as so many others, lacks a fundamental option:
importing your private keys to attach your crypto without having to pay any fees. For example: I have 4000 REBL. I want to exchange some of it to cash it out, but, in order to do that, I need to transfer some ETH I already have in the exchange. Well, it seems that I need at least 0.11 ETH to cash it out. For me it's a lot of money. If I would be able to just import the private keys of my REBL to the exchange, I could transfer all of it for free, then sell some, cash it out and withdraw the remaining REBL to my wallet, this time paying the fees that keeps bit-z afloat (and, of course, to a completely new address and wallet).
