I would work hard, try to find more jobs, maybe sell some things which I can live without, make safer/more likely to win straight sports bets instead of parlays, which I usually don't do as they don't offer good odds but they are far more likely to win. And last but not the least, ask for help from my friends and family. Depends on the situation though, like how desperate it is.
if i am in desperate need of money, i will find a good way to have it, like having a sideline work which will immediate earn money, or i'll ask for my friends to lend me some. in bitcoin, i will join any champaign that i am qualified for me to earn money. there are many good ways of earning emmidiate paid services, and there are so much friend who are kind hearted who are willing to help.
