I think the right thing to do is to launch it now and see what other features can we recommend, it's hard to get the whole picture in words alone, send us the blog and we'll see how good it is the big difference from your blog and from predictions thread here is people are getting paid for their prediction and opinion and that's something that your blog cannot come out with unless, of course, you have a big fund to spare s you can invite people to participate in your blog.
I plan for start to give 300$ a month give away for the 3 best people. (Who have the best predictions) every month.
Later on it will change. When I have a lot of data on the site.
if someone will want to gain from his prediction and followers he will be able to make his predictions hidden.
And people will pay him 30 $ a month BTC for example to unlock all of it.
People who beat the bookies can gain a lot of money from their predictions and their followers.
