This is called gambling. High risk, high reward. When you saw that you were up by $700, you weren't satisfied and thought you could make more profit. You decided not to cash out your profit. So you were taking more risk to get more profit. But things didn't go your way and you ended up losing everything. Now think, was it worth taking the risk? How much more profit you would have made if you took the risk? If it was for like few more bucks, then no, you shouldn't have waited till the end and should have taken your profit. If it was like a few thousand more bucks, then yeah, I would say it was worth the risk since you initially placed only a $70 bet.
This is gambling on where you do need to make out choices, decisions will really be depending or basing up on how much risk you would really be able to put on and this is where choices do been mold up.
Each of these decisions does really corresponds results and if you do choose up on cashing out midway then its your choice but bare up on the money that you had gained up which is only a fraction
and its impossible that you wouldn't think about the whole winning amount and this is where emotions do really take place.If you are really that not being mindful about huge wins
then pretty sure you would be sticking out on cashing out early as long you do able to see that you are really that gaining.
