What do you do after you suffer a huge loss?
If you have more money would you again take the risk and invest or would you just stop trading and try to earn in some other way?
Everything depends on the character of the person, many I think, will want to analyze their actions and all the miscalculations and already make a completely different scenario. And others would simply find a replacement with less risk.
It especially depend on the circumstances of that person and whether he can afford to loose that money or not , because for some people it is very hard to recover from a huge loss not just mentally , but also financially especially people who are new to the field and that have invested money that is necessary to satisfy their basic life needs so they are getting a loan or borrowing from someone to cover their losses which might not be beneficial or encouraging as a 1st experience for somebody who just started his business .
If it's up to me i'll certainly try to win back the money because there's always alternative solutions and many good projects that just lack people to believe in them and give them the needed support to succeed .
