But once you are a foreign labor in a particular country, you die die hope it will be strong against rm.
On my last 3 months working in Qatar, the weak rm/riyal period I gained about rm300 each month extra.
Not to mention my friend that taking USD salary, he gained extra rm0.50 for every USD changed. He got about USD30000, that's rm15000 extra when he changed to rm back:w

If local consumption, nothing much will happen.
So don't simply spread rumors.

A chemical coffee sold in Qatar is rm17 while in Malaysia is rm16.
His salary is rm30000 now compare to last time of rm9000 when he still in Malaysia.
But again, he is still a Malaysian, so have to come when the time comes.
