So how much can you make using martingale? It seems very little then.
I have tried a few runs with one satoshi as base. At lucky times, I made 200% the amount in one day while I have lost 0.001 within seconds on many other days. Your expected profit is and will be negative since House edge exist, people only use it because they think they can succeed.
Do you have any screen shots of you doing this? I think that it is very far fetched that you could have tippled your money using the martingale system.
