Most likely, when speaking about gambling, the author means sports betting. If this is really the case, then there are two fundamental approaches to this matter:
1. Try to win a large sum by making small bets over a long period of time (or, as the author put it, try to win gradually).
2. Try to win a large sum by making large and carefully thought-out bets over a relatively short period of time.
It is difficult to say which of these approaches is better. Everything depends on the character and worldview of the individual player. For my part, I can say that for some time now I have begun to lean towards a small number of carefully thought-out bets on large and medium amounts. Simply because it is difficult to find many good bets. Each bet is too unique.
Your first recommendation would be a very effective strategy for a new gambler if they are betting small amounts. I started with this method when I started betting on my gambling platform and it was a very effective method. I recommend this for those new gamblers because they are completely new to the gambling industry and need to gain more experience in gambling and reduce their losses. Trying to win gradually will help you stay involved in the gambling industry for the long term and become experienced in a short time.
By implementing your first recommendation, it is possible to be successful in most cases in the second recommendation. The first strategy you took, such as betting small amounts and trying to win big bets by becoming experienced.
