It does matter buddy because the user purpose are the wagering contest, to also win his bet and to have longer wagering time, so it better if he mix strategy but I won't advise him to use the martingale strategy due to the risk involve.
@Betwrong was right the guy was actually mixing things.
Martingale strat is considerable on catching up a wagering contest but it is more riskier same as you said but still an ideal way on catching up numbers.
Its a matter of choice though or simply if you can able to handle it but for me it is way more better on catching up high multipliers with that minimum bet strat.
