At it´s current state, bitcoin is viewed as digital gold, driven by the idea of value preservation or quick ROI, even thou it is very volatile. It is by that definition, just like many other cryptos an investment venture. I agree with your thoughts and even bitcoin could evolve into a payment method, even if there are better coins out there. When looking at the whole crypto space it is not a investment venture but many or most users still only hold coins for ROI not to use it! The usability of crypto is still so low, but the potential is there, to go beyond being just an investment. When we see usability that generates value for companies or when companies realize they can save energy and time, blockchain will have evoled into a very usable tool.
We are living in an ever more global world and blockchains bring us closer then ever, we can send money or documents to anyone anywhere without third parties and with 100% anonymity, this is not an investment, but a strong reason to use cryptos.
In my view, decentralization and privacy is what it is all about and I both use and hold different assets, as investments, like most do, but also some that is intended to be useed for a purpose.
We should absolutely promote good projects, but also promote the intentions behind blockchain tech and it´s potential!
I use / used STEEM to blog and to buy a few things, I use DeepVault and DeepOnion to send some funds(anonymous) and store documents, bitcoin to place bets yeah the list goes on, we need more adpotion so we can spend / use more of the cryptos
