Some notes:
- Volumes have been as high as 2k btc/day visible here http://cryptofresh.com/assets It's usually comparable or bigger than many smaller altcoin exchanges.
- There are numerous bots for all major pairs that will fill your orders completely most likely even though they aren't visible on order books. That's primarily how I do it.
- You can use bridge service to internally convert assets even faster for some fee but with good liquidity.
Hello I'm trouble finding a bot myself, do you have a download link?
