2) As a message to governments. When governments see how easy these altcoins are to start, it will help show the futility of trying to get rid of Bitcoin.
I hope that some of you reading this will consider spending a few dollars on some altcoins. Not to make money (expect to lose most of it), but to support cryptocurrencies in general.
They already know that some countries take it positively some negatively, they know it's futile to stop these companies, institution and individual from creating new coin so they prefer to regulate it some other ban it like India.
I'm already investing in altcoins because they are here to stay, because this proves altcoins has purpose and they have usage to offer to humanity.
