In his latest missive, Clif High, expert in predictive linguistics, promotes the idea of purchasing the new cryptocurrency Populous (PPT). You will need to buy the Populous tokens from their website -- www.populous.co -- and go to their Pre-ICO tab. You must have Ethereum to take advantage of this opportunity, but the Populous website states it will give bonuses based on the amount you invest.
This may be a speculative venture, but Mr. High has a good track record of success.
