I have a few Actifit tokens but never used it much as the next day they are void. I don't tend to write my content the same day as what it is about. Too much hassle for me.
Just tag something and 'earn' even more 'money'.
Makes things interesting doesn't it? Though if you stake them all, it's just more advancing ranks coins (Minnow, Dolphin...) etc....
I can only really stick with a few of them. There seems little point in chopping and changing. I was using #zzan for a while but if you look at the site, it's all Chinese. I may trade it in for something else.
