There's no interest in this stock. It's dead.
SEC actions deliberately sucked all liquidity from the shares, and made it impossible for the directors to pump this gray stock.
Those left holding shares have nothing but high hopes of 'things going on secretly in the background', shares that are hard to sell, and losses they'll not recover.
No money paid to REVO, under the agreement with Eyetalk365, will get to REVO shareholders. It has has been diverted, to pay loan notes issued by the directors.
There's no evidence that Eyetalk365 is paying any of the 40% royalties due to REVO. And REVO isn't about to sue them for breach of contract.
But, if you disregard all of the above, REVO is a heck of a stock to be invested in.
