Not familiar with these two "RCashOnline and "The Saint John of Jerusalem Knights of Malta Foundation of the Philippines, Inc." but the other ponzi scheme who used to be called "Forsage" does really make a noise which eventually managed to persuade numerous Filipino citizen including few of my acquaintances.
I also have some friends in Facebook that is advertising that Forsage company but I don't want to invest on it. Yes they are using ETH platform and blockchain but most of them are posting "They don't do anything but they are earning" which is quite skeptical.Even though SEC didn't post warnings about these kind of scam, I knew it already that it really is base on what the participants posts and the way they are earning
. They are just rich on the dashboard and that's it .
