Some inexperience gamblers think that they bet big cause they will win big but are they ready for the consequence if ever they lose, things that experience gamblers warn them about lady luck is not always on their side. We bet $1,000 for now and if ever we lose we will lose that $1,000 for now and later on we will bet only $100 to get back that $1,000 do you think that is a smart move? No. We bet big all we have right now if ever we want to win it all, we have $5,000 right now we bet it all now.
Based on your post you are calculating loss, winning, and profit, these are all possibilities and assumptions there's no right answer to this you could be right and you could be wrong if we based your bet based on your calculations you can get all your losses and at the same time you can lose everything and the one who advice will get the blame.
Similar things happen to me in the past I just suggested a possibility and when they've lost everything I get the blame, but if you are not going to blame anyone then bet everything for a win or lose everything because the longer you wage the house edge will come to play.
Again this is gambling no one knows the outcome, the only thing we have control of is our acceptance of the results.
