Is electronique trading very safe?

let s first mention the famous statistic that says 70% of traders are not making any profit
then add to that these secret cartels that manipulate price
and finally tell what a very known and wise person had said that trading commodities (or currencies and stocks) by distance something like electronique trading is inadvisable just because price can be manipulated as well as supply and demand

that same wise person had also said that " trading is the most and best work a human can have"
and that is why we all love forex , it has made trading available to common and ordinary people with low capital the sad thing some bad fish are making the business stink

its can be safe but not for all time , the result of this kind of trading is just for temporary session , not for permanent something at all.
