I always do parlay bet by combining low odds bet mostly below 1.5 odds until the combined odds is over 2.0. I have much better profitability on doing this method rather than straight bet on each odds since 1 lose bet will wipe out 100% of my bet while my profit is just small when bet win.
At least on parlay bet you have higher profit by relying only on combined small odds.
I always make sure that the odds in my bets are not lower than 2, this works well for me. And it does not matter to me whether it is a single bet or a parlay, the most important thing is to adhere to the odds criterion. But this approach will only work if you win more bets than you lose, everything is simple and clear for everyone. More often I bet a parlay to achieve such a coefficient, but I am also in no hurry to play too high odds, maybe even because I have already gotten used to this order and do not try to change anything.
