So my question is do these same companies also do stock and allow their company to be funded both ways?
These companies are start-ups. Start-ups don't issue stock in the public sense. They seek investors. Releasing ICOs is a great way for a company to generate capital for their company without giving up any ownership in return for those early investors.
Stock is ownership in the company. ICOs don't offer ownership in return for the purchase. But what you are getting is something that can be traded easily for other cryptocurrencies or for fiat currency.
But be careful with ICOs, examine and consider their business model carefully. Most of these ICOs will fade away into history.
ICO is like IPO. It is similar to penny stocks.
Yes its like IPO by selling tokens they gathered capital but its decentralized.
No, man, it's not.
Regarding "stock split" like maneuvers, it's already happening. Keep your eyes open for the various BTC forks such as BCH and BTG.
Hard forks are not stock splits. A stock split is when a company wants to double the amount of shares they have outstanding, they split each 1 share for 2 or more and then the price per share is halved or reduced by an equal proportion. At the end each investor has more shares but the save value of investment.
A hard fork is a coup attempt. A hard fork attempts to take over an existing coin and in the process they need to grant the current holders of the target coin an equal amount of the new coin to generate demand.
