As long as they are making a good progression everytime then it should not be worry, except they are losing much coin then it must be questioned. Because I still prefer site with slowly progress instead of faster but no result in the end. You can compare most of the site which has slowly gain amd faster gain, the result will not be the same and have so much difference
whenever i invest forward , the backwards step i take are in perspective of looking sideways at all the things above me.
i must be throwing my gains slowly into the wind then i can quickly reward before i step in the quicksand. this is when i truly know i am me.
