With patience you'll do well in OPL bro, no doubt, but when your broker allows it try to buy directly from the TSX.V instead of OTCQX, because its always better to buy directly from the exchange where the company is located. You can buy them on the OTC if you wish tho, there is just not so much liquidity as with the TSX.V, but that will change once the company has changed its name into POET Technologies, because after that a PR campaign will start and the American investors will pick it up. No matter when you start to buy, or where, everything you pick up under 0.50 will be a ten bagger once this technology is sold to the highest bidder, as $5/share is the minimum you'll get for it!
