The beginners luck is a big attraction of gambling sites. Myself too experienced it during my initial days of gambling. This drives the beginners go further with big funds. Myself had good luck, but the same didn't last as I don't have control on money management. Later the mind never accept the defeat and want the lost funds back. In the race of recovering the funds I'm running for years.
One who has experienced the losses on gambling can easily stand a chance to profit and experiment trading.
The thing with beginners luck is that due to the fact that you have not gambled for long the variance in your results is going to be at the highest point of your gambling life, some are very unlucky when they gamble and they may never gamble again because of it, but when someone gets lucky at the beginning of their gambling journey they may actually think there is a way for them to beat the casino and that is when they use a big amount of capital only to lose it all later as they have not realized yet the power of the house edge.
