In the First place you should you were expected to be certain who played the game. I don't think it would be necessary of your friend would claim to had played a game he never played all to gain influence of a risky gambler on you or what?
I expected you to talk about if the gammer won the bet or not instead you ended up saying "if you were the one you would had cashed out".
However, whoever you agued with about the game is right.
In the first place it is being risky in investing on gambling because it has you no assurance of winning.
Okay let's say you gambled on a chance-based gambling aside the skill-based gambling that you may be some Little sure trusting your skills, you are then apparently 99.99% sure on a risky play because you don't know how the system is programed or what the nature of the game may posseses at its end.

How would one in the first play invest with a range of $10 and expecting to win $100 with the stake with no stress in just matter of seconds, hours for a just a day?
What ever the nature of gambling would be, it is indeed a game of greed and change change it.
Though such a game as shown if lost at last is apparently a greed. Such person's are likely not beholding to responsible gambling.
Well. This is depends on my net worth so if that of your friend maybe worthy enough and looses the game, the $1M may be seen as a mere $1K worth loosing to him and not me who feels the wraths at when I looses $50 in a casino.
