You are not too late ! Two weeks ago the network was 2MH/s and the price arounf 0.18. Today Network 9 MH/s and price around 0.45 .You are in the next great position to invest now. You want to guess the numbers one month from now ?
Buy, or mine?
My choice is buying because the price went down today a little bit. Mining difficulty is already high and you will need a good mining hashrate in order to get a decent amount of MSR/day/week/month.
