Play high and risk a lot, a short session can make a large win. It can lose large as well.
Let us do some math. If and when I claim I won 100000 Euro, over time, very few even believe it.
The same person can claim it is easy to make 100 Euro a day, and some even an hour
The first should make 100000 Euro in Three years, the second in 1000 hours, which is a few month, if it is played full time, and it would be so, with such a results.
Most (large) Winners have a lucky streak, and are not scary, use the bank with care.
If we dare for example to parlay a bet on a single, we lose most of the time, and have a chance
to recover a small loss using other strategies,
I did dare to parlay a single with 5 Euro bet. I did it from time to time using small winning, and
after some time it hit. Large wins is something which happens if we dare.
The way is to hit with a positive progression, if we dare to stretch it, on a positive progression we lose most of the time. With negative we win most of the time, but never much, and a loss is large when it comes, large as the win using positive progressions.
We can win large betting large, but few can risk large Money, and stand a loss. If it is Money
just won, it is different.
If we play to "stay in game" or break even, we may win, but not to change the Life at all, rather
wobble around the Money we can lose, or in worse case losing more than we can stand.
