This is a good idea you have shared OP. I am curious to know more about this. Do whirlwind have their own mining farm or they are affiliated to another mining farm let us know because from what I see, whirlwind are mixers and I believe they are doing just fine with that investment. How come So soon it is a mining farm with a 12% APR daily yield rewards. Is it not worth explaining so we could know?

Lastly, it seems there is a glitch while you were trying to upload your image content. I think you should try uploading it again or you edit and do the needful so as to help give proper pictorial explanations.
