Kudos to Btc-Arbs for posting here and making the repayments more public. And more importantly, EXCELLENT work to everyone on the forum for building and maintaining the repayment spreadsheet.

My advice to Btc-Arbs: Pay off the smallest accounts as soon as possible; certainly any that are less than 0.25 BTC to get them out of the way. Make your job easier. Stay in contact with your larger customers and keep a steady flow of coin back to them as well. Also, set up social media accounts (Twitter, Facebook, etc) and announce those accounts here so people know they are linked to you.

Everyone with larger balances: I would not expect all amounts to be repaid within a short time frame of a month or two. The admin at Btc-Arbs has already shown that he is over-optimistic with his promises. Based on the very limited information available, I believe he uses an arbitrage system that is sub-optimal. In other words, his system is inferior to the one I use - I have a good sense of my profitability, and the days that I make those profits. I would not expect to make 350 BTC within a month or two, so I do not think he can either.



If anyone is considering a future arbitrage program, please take this advice from someone who is doing the real thing:
1: They will not accept small deposits. As Btc-Arbs has discovered, managing several hundred customers can be a nightmare when all of them want a response at once.
2: They will not post daily profit reports, or at least will post a huge caveat with the report. Arbitrage profits are NOT simple arithmetic. A good system may use quantitative analysis in addition to arbitrage, and this complicates everything. Also, there are occasions when the buy and sell happen across midnight (thus they are on different days), so a daily profit does not exist for these trades.
3: They will have a system that provides security and separation of machines. The arbitrage platform will not be on the same computer that hosts the website, and another separate computer will be used for customer interaction. Overlapping these systems is pure insanity for any business, and suicidal for a bitcoin-based business, as Btc-Arbs has sadly discovered. A half-decent hacker can create a custom trojan and try to send it through the website or email - and very few (if any) antivirus programs will detect a new customized trojan because it is not in their dictionary.

If you see a program that does not satisfy these three basic conditions, then look somewhere else.
