If the aim is to earn low profits daily, gambling is the least suitable tool for achieving that. Nevertheless, if one finds it entertaining, why not to try? After all, any strategy can fail at some point, and the strategy when you earn each day 1% of your balance is no different. There is a possibility of it working for years, and surely you will not lose your balance faster than in 100 days while strictly following this strategy
1% daily is actually a huge amount
For starters, that is 30% monthly (without compounding). If it was in fact possible to earn so much without busting in less than no time, casinos would be ruined as quick (as there would be no lack of people trying to exploit this strategy). The truth is, if you are going for that target, your bets will be risky as hell, and the possibility of running it for years is really minuscule. More likely, you are going to lose your balance in a couple of weeks if not days
We all know that only half of those bets are going to be winning ones, so no one is expecting 30% monthly profit. Most likely, you will lose 16 bets and win 15 because of the house edge. Regarding the time span within which you can lose your balance, it can't be a couple of weeks or days. It is around 100 days if you risk not more than 1% of your balance each time.
~ Additional 1% every day would be huge; it's up to luck if you could do it.
As far as I understand, we are talking about betting 1% of your balance with 50% win chance, once per day. It is hard to expect 30 wins in a row on 50% win chance, and if you make just one bet per day, it makes no difference, it is still very unlikely. Overall, this strategy can hardly help you to earn money, but it can surely help you to last longer with the balance you have.
