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.
It is why he wants to quit trading because instead of calculating profit, he is calculating his losses and he is more afraid to lose.
That's not bad if you are going to quit if you think that you aren't going to grow but still you've got enough capital.
Once you already invest another amount then he can possibly gain his losses only if he has the guts to do so.
40 bitcoin left means 40 x $1,200 = $48,000. he is not in loss , he is on completely profit more than 400% !
