Its depends on how much of it you put into action per bet, how many bets you place, and your playing strategy.

Its a very complicated area refferred to as “risk of ruin” or RoR for short.

It involves complex formulas with input variables that are complex to figure, and often arnt known by the average gambler.

Heres a solid fact for you to consider though, no matter what you do, the probibility of you losing it will be higher than the probibility of doubling it. And the probibility of losing all of it will approach 100% as you play more and more trials.

Dont play blackjack online.

Don’t play blackjack online… go to a casino. There you can pick the level of table you want, 5, 10, 25, 100, 500 minimum bets. And playing with people is more fun. Online shoes could have an infinite number of decks in them, I don’t know really. In a casino, there will be 5 or 6, allowing easier card tracking (counting).
Don’t play with money you aren’t willing to lose. I play at the lowest table I can find a seat at, even if I go in with $1000. I set a limit. If I’m down to 25% of what I started with, I leave. On the other hand, if I’m up 250%, i leave also.
To play smarter blackjack, research the hands. Don’t do silly things like splitting tens or doubling down on hard 12. Decide wether to hit or stand on 16, and do it EVERY TIME. Find a system that works for you, and stick to it. I’ve made lots of money playing blackjack. It’s fun!

blackjack is a game of house advantage so whatever strategy ou choose you will probably lose, but if you dont mind losing this money then its okay, you can put a sum that wont make you feel bad for losing it.
