I was usually doing 100 or 200 for 12+ weeks. I use the standard rate for them. The last one I tried was 20 weeks and did not go. Next time, I plan to do 100 for 12 weeks and hope for the best.
Now I have my son to think about as well. His 500 is almost done and he will need more or he's a tiny minnow again. I have on my list to get you on his steemdunk. He is so busy we can barely talk now.
I was thinking of trying a longer term like 26 weeks, but at that point to get the ROI high enough it felt like I should just buy some SP instead. Think that 12 weeks is a good time frame to have time to capitalize on the investment you make.
It's really nice that you are helping boost your son and get him going. Hopefully he realizes the opportunity he has here.
Thanks for getting him to add me when you get a chance. Every vote helps!
