IRNC is a high risk speculative stock and my advice to you if you going to position yourself with this stock invest with what you are willing to lose and as fast as it goes up that is how fast you will have to sell. If you are doubling, sell half to take your initial investment out then play with the profits so that if you lose it you lost the profits, the money you really did not owned from the beginning.
Keep this thought in your mind, you presently own a percentage of nothing and with a bankruptcy filing or a reverse split it will be painful unless you invest with the expectation that you might lose it all being that it is a high risk speculative stock.
I am a shareholder and with stocks like this I will only invest $500.00, at double I sell have my position to take out my initial investment with the hope that the profit I left will continue to rise.
If you don't care how much you lose then invest what you are willing to lose.
The above in an opinion I am giving from my young experience and remember, penny stocks are always hyped among shareholder because they think hyping will cause more people to position themselves in the stock to get the stock moving, it does not work like that, what works like that if the stock is being manipulated.
I wish all you to enjoy the fruits of your investment.
