Why would this kind of penny stock increase so much in value?
Well I'm not going to advise whether it's a good idea to invest in this company (though often OTC is pretty scary), but it DOES have a product (vivio, an ad blocker), it did post financials and it's trading on the OTC-QB (which is better than the pink sheets), so you need to look these over and study up on the product to decide if it is overpriced or not.  What might have occurred (viz the Patriot Berry Farm becoming Cyberfort) is that the latter bought up the stock of the former (this is, I believe, called using a shell, which is not necessarily a bad thing) and is using this as a way to be registered, i.e. sell to non-accredited investors via the OTC market.  So I'm really just answering your third question:  yes, you have to do a lot of due diligence to see if buying this stock is a good deal or not.  It might be the next big thing.  Or it might not. It certainly is the case that low trading volume allows a relatively small trade to really change the stock price, so the penny stocks do tend to be easier to 'inflate'. Side comment:  the bid/ask spreads are pretty big, with a best bid of 0.35 and best ask of 0.44.
