I did a spreadsheet for B.EXCH buying 30 days ago and selling today:

You will get a Monthly ROI of 8.155% (nearly 100% APY.) This includes the dividends and the less 2% buy back fee. I don't know what the risks are i.e. Havelock up and disappearing, the Manager getting hit by a bus or otherwise incapacitated, etc.

Not knowing 20's real name is not a big issue for me. Who knows the name/team of the specialist or market makers in the stock market? Probably all just some computer clacking incessantly in the corner of an office somewhere...

But really, Panama?
