Multibet bets involve high risk, which is why it is necessary for people to always make multibet bets that have very high odds that compensate for the risk that these people will be taking when they make the multibet bet. I usually say that making multibet bets is the same as testing your luck, that's why when making a multibet bet the person should not put a lot of money into the bet, for example here in my country there are many people who make sports bets and have chosen to do so. multibet bets in which most of the time the total odds value of the bet is above @300.00 and they only place $1 on the bet. I asked why they do this, they told me that as they are running a high risk of losing because in their bet there are times where there are more than 17 teams.
so it's worth it for them to put just $1 because even if they lose they won't be missed, but when they win, then they will win $300, there were many times when these people from my country managed to get the multibet bets they made right, once someone showed me a multi bet with odds of 500X and got it right, with that the guy won 500$, the following week he won again 600$ with just a bet of 1$, then he had many weeks without a correct bet, but from 17 games that he puts it in his parlay, he can hit at least over 13 games frequently
and this includes teams from many different leagues, this shows that they know football very well, they are not based on luck, they are not based on odds, they are analyzing the teams exhaustively and after a lot of analysis they are able to choose the best market of the game to put in the parlay. even if they were placing $1 each week and lost throughout the season, they would still be making a profit, because they won a lot of $500 and always bet with $1 on multibet bets with odds above @300.00, by which I mean that the only strategy, if we can consider that as a strategy, and that the person knows how to correctly analyze games
For sure multi bets are very risky and it's easy to get sucked into it if you don't know what you're doing.
In my personal opinion anyone that wants to try placing multibets should do so betting a small but stable amount each time. You don't actually need to bet more than 1$ for each bet as you said because here we'll be looking towards building high multipliers.
If your strategy and intuition works then over time you should be earning more than you lose. If it doesn't seem to be working, you can quit any time. No need to create big bets to recoup losses, since if you were betting small amounts the total of losses should not be that significant.
