I like to place such bets, but for small amounts. Moreover, it is in Formula 1 that the most unexpected wins occur. A lot depends on what happens to the favorites (an accident, a broken racing car, a long tire change, etc.), so the underdogs have a chance. Then even a small bet gives a big win. It is impractical to place a large bet based on such a combination of circumstances, because in most cases bets on the "dark horse" lose.
If you enjoy doing it you should keep doing it, in the end what matters is having fun
then i understood that you use small sums of money, very small indeed
so why not, you know very well that you don't expect victories and you do it for fun, everything is fine, in fact everyone should do like you: play a little for fun
