I never heard for such trading bot before, I noticed this topic accidentally. Can this bot make good profit, and what risks we have here?
Yes, I use such a bot for trading.
Custom developed, it integrates via API on several different popular exchanges* and generates passive income for me via arbitrage (buy bitcoin cheapest possible on x platform, sell higher on y platform). Daily profit varies obviously due to BTC price fluctuations, arbitrage fluctuations, etc. If anybody is seriously interested in it and has a decent offer, PM me

Not willing to release it publicly however for obvious reasons.
*you must have valid and existing accounts on any exchange you want it to use.
I will open accounts on exchanges where I don`t have it, do we need to be connected on more then one?
Can you share more about your experience, where did you download that bot, how much is your starting investment. Did you make any profit, did you lose something? Tell about exchange sites you use. Thanks in advance for all informations you can give.
