It's very easy to win like that.
When currency A was 0.5$ from B, I converted everything to B, when the price of both was close to 1$ , I returned everything to A.
I did this several times, on volatile days I did it twice (4 operations).
Interestingly, the money did not increase, only the amount of coins increased. Another interesting point is that this spreed between them has remained in this same variation for around 20 days. I'm enjoying...
Matrix failure?
