As experienced investors are there measures that can be imbibed by new investors with little capital to help boast their capital. Some will want to mention patience which I will agree to but in situations where the money is needed to meet an emergency need how to you tackle such situations. Your formula might be a saving approach.
You tackle those situations by not investing money you can't afford to lose in the first place.
Getting a stable income
first (as pointed out by Mr.right85) and
then using DCA,
if you can afford it, is unfortunately the only way to get started in such a situation.
