This is a risky stock for sure. No more so than any other company with great potential but nothing proven. But another poster said on here earlier, when it's proven, you'll pay a much higher price and it will be instant - either you're in or you're not. But looking at the charts of other successful companies, you'll have plenty of time to get in and benefit from the growth – unless they are taken out that is. For those who are in at higher prices and are nervous, I see plenty of bids ready to take the shares off your hands. I will be adding my bids soon too – just waiting for the market to scare.
