I have calculated all my trades on the various platforms i have used in the last couple years.
Deposited: 47BTC (roughly)
Withdrew: 40BTC (roughly)
Overall i am happy with the results, i would pay 7 BTC anyday for what i have learned so far.
Now the question is: what the fuck do i do now with my money.
That is a really big investment, I don't think you should stop trading, I mean you was deposited such a huge balance (I think) and with that amount I could get many profits. I don't want to say that you aren't a good trader but maybe you should read more before decide to start trade
