I think these are very exaggerated calculations, do you think owning 0.06624605 BTC will make one really rich? Then most people would be more than just rich!!!

Most predictions expect that Bitcoin will reach its highest peak of one million dollars, so if Bitcoin reaches this peak, then 0.066BTC = 66000$. Does this amount make you rich???!!!

I don't know on what basis Kemper made his calculations but I think they are wrong.
