1. Don't bet all your money on one bet.
I agree with this statement because diversification has always been the key if you want to go far and succeed. There is this saying that only a fool taste the depth of a river with both feet. This saying is very applicable to your statement. If you bet all your money on one bet, you could win or lose it all at once but when you split it and bet on different ticket there's a chance you could win some and lose some.
2. Bet the same amount on every bet.
I don't agree with this. I use to bet on multiple tickets at a time but my staking depends on how much confidence I have on the ticket. I stake high on some while I stake little amount on some.
3. Don't bet more than once a day.
Well, in as much as this make sense, it will be very difficult to practice. Especially in sports betting, some tickets burst immediately after the kick off due to some mistakes and one may be tempt to rebet if you believe in the rest of the games. Even if I agree with this, I don't think it can be practicable always.
4. Don't bet every day.
Totally agree with this as it will help to prevent one from being addicted to gambling. There's more to life than just gambling and you need some break to cool off your brain and do something useful.
