Yes, gambling as your exclusive source of income is definitely not a bright idea. Had a friend try that. He was so convinced that his scheme at the casino was brilliant. Unfortunately, he had no self control. He brought me along for a few days so I could help cut him off if he lost too much or reached his profit target but couldn't walk away. You can guess how that worked out.
Every time a broad market sector( ie energy) or national stock index (ie russia) crashes go all in and double your money, rinse and repeat.
So, the bank taking your bet will just give you their money ? How about they push the prices lower to force you to give them your money instead ?
Well, what do you want from me? Figure out for you where you have to get in and ring a bell? That's your job, I just gave you a tradeable idea. Thank me for that.
Why would where you get in matter ? Is it not worth the bank's trouble to move the price to get your money regardless of where you have placed it ? What I want from you is something that is less of a loser.
I know someone that paid $1000-$1500 for a cell phone repair kit. One of his stores charges $60 a pop. There will always be a need. I know I broke my Samsung Galaxy trying to fix it myself. Ha. Ha.
