No one can answer this question for you. Buy, don't but, take a small position and average down if it falls, grab allot of shares, hold and sell profits.... it all depends on your tolerance, funding situation, short term or long term goals, the rest of your portfolio and to some extent your age, family, personality, etc.
It sounds like you have not developed an investment strategy yet. If you are new to investing, (and I am not a pro at this by any means) I suggest you set a realistic target for the year, talk to your accountant about tax liability and examine what works best for you.
The sub pennies were a whole new learning experience for me. I was used to the trading on NYSE and I made some rookie mistakes when I started. Stocks like EXPH are not Ford. Personally, there are few companies at this level that will ever be a Microsoft. That said, this company has long term potential. Try to find subs that want you to come and visit their enterprise and will give you a tour. There are not many. Most are a rented suite or a PO box.
I nibbled and accumulated. I will probably still be holding in five years. This will probablly be the only sub penny I own now that I can say that about. (well, maybe one other) I am allot slower to take profits on companies that I have done my DD on because of tax issues. They can't tax unrealized gain so you can grow net worth and not be taxed. Of course, that can be risky as it can disappear tomorrow. It is all a huge high stakes poker game with a chess /monopoly mentality. Financial football.
My advise, too much unverified info out now to start with a large position. Too much positive info out there to pass.
Good Luck!
