I went to the University of Chicago for my undergradute program in Economics, and I graduated from the LSBF. By the way, I calculated the ROI using the CASH FLOW netted of the small fees that I had to pay for the BTC transactions and for the currency trades that I did. I usually work with currencies since I know really well the foreign markets. I didn't mention beforehand that I did this job, while making a world round trip with my friend. However for the ROI my friend I used the following formula ROI= ((TOTAL INFLOWS-TOTAL OUTFLOWS)/TOTAL OUTFLOWS)*100. I also said that I increased my capital by 400%, but if you look at it from another point of view, my ROI is actually 300%. Here you can see the cash flow. PS: I will print out the totals I had at the end of every successful trade or transaction. It will be a good row of more then 100 trades. I am not really good at HTML so I don't know how to insert a table. Also I would describe myself as a very careful trader and broker. Just to let you know, I always studied on loans, since my family was always very poor, so I could't afford to loose money. I made also a lot of friends around the globe, and I keep in touch with them on a weekly basis. This gives me an extra insight on the conditions of their government and market in a much more reliable way then the newspapers do. It's almost a sort of insider trading. I don't invest a lot on companies, since it's too much corruption and volatility nowadays. I do invest in good projects. My last investment was in solar roadways, which I personally like, but I bet it will be a good investment since it will get a good support of the gov't. By the way here is the extract of the netted cash flow, so that whoever wants can make his own calculations.

Ah, I almost forgot. Both me and my friend invested 5000 each, so we started out with 10000. The last number was made 2 months ago. Afterwards we paused it and started the research of opening a company, which will not be based in the USA because of really high taxation on investment matters.
