Is better to use small money or learn risk management first before investing especially newbies.
The point is, people just want to make a hell lot of money at once and they did not want to start investing from a small amount because they know small investment brings small profits and big brings big profits. And this logic has been inscribed into the minds of young ones and most of them just waste their time for getting investment money from someone (maybe a relative, parents or any person) and once they got it they seek ways to invest it, in ways that they don't even have to work for it just put their investments and wait for profits.
This is just chaos, i have seen so many practical life examples and tried my best to teach them the basic rule you have started, but still, any fail to acquire it too. i know this rule seems so simple and many intend to ignore it but simply becomes hard when time passes and you have got no more of it.
