How much money should I bet?

There is no right or wrong amount to bet with. What matters the most is that you decide on a budget and stick with it. If your bankroll disappears in two or three bets, what good will it do to your winning aspirations? You must allocate an amount to play and not exceed it, regardless of the result. Ideally, after winning a bet you can and should withdraw the amount you bet. That way, you are only playing with money that you have profited and therefore cannot lose. The same goes for the amount of money you want to place per bet. If you have €50 available, you should never do €20 bets. Don't be afraid to win a little at a time, because it's better to make little money than to lose it all in a few moves.
