How did you increase your investing money?

In order to achieve our crypto goals( many men's dream is to become a wholecoiner for example) we have to be perseverant and do sacrifices. For example, I have managed to stop smoking, although this was the hardest thing to do. Since I was smoking 2 packs a day, I managed to save $16 daily.

What have you done throughout the years to increase the amount of investing money? Maybe you have stopped doing some kind of expensive activity or maybe you found interesting side hustles. Looking for the most unusual and effective methods.
