Flipping and leaving things down to chance is the easy way. In turn, sometimes you will win, sometimes you will lose. Ultimately, 50/50 results in long term even events. Even wins, even losses. With casinos, this goes down as low as 35%/65%. In online casinos, it's generally 45%/55% or sometimes as low as 49.5%/50.5%. The result? Long term losses.
Day trading involves a lot more than just chance. It requires following principals and skill to improve the success rate. You are also competing with and against many people in many markets, not against a casino software built to always have better odds of winning than you do.
