continue or cashout ?
Depends on what you want.
Are you going to continue gambling even if you withdraw? Than its not much use to withdraw the funds as you will end up depositing it again anyway.
You can always withdraw the profits and start from 1 btc again.
Looks like a good profit in a span of time. Have you done martingale strategy on this ? Judging by the times of green and red rolls, it isn't just a basic martingale.
It must be some hybrid betting or maybe random manual odds.
Anyway, you should continue cause as what NorrisK said, you will start it all over again - deposit and play. Add the profit to your bankroll and it will increase more bet chances before you lose it all.
