With an profit of around 430 Satoshi per 1000 rolls(tried it myself, have lost almost everything while trying

), and assuming that each rolls take 2 seconds, it is approx. 700-800 Satoshi per hour.

If you look at it, this shouldn't be such a hassle on OP because as he stated, his laptop is always ON. But doing the calculations, you would earn roughly 1$ per week. Is 1$ more than what you'll pay for making your laptop ON all the time? I hardly think so. Electricity is expensive in majority of countries.
700-800 satoshi per hour? You might want to just solve a captcha in any faucet site. 1000 satoshi/hour is the average reward for doing faucet. I think this is much better than keeping freebitco.in tab on your browser.
You might want to think of other ways of earning as well. 10$ per month is so little tbh. Also, drop the martingale thing. There's a possibility that your allocated losing streak will be surpassed in the long run, making you lose all your hardly earned money.
so in short its a total waste of time. Im not discouraging the OP but he had a very terrible stragedy income add on the martingale as you said, those are pointless techniques youll still lose in the end. your 1 month earning $10 would gone in a blink of an eye then youll better start crying.
