In my opinion bitcoin was developed as a way to create and transfer money. For everybody.
I don't think that it was intended to be a form of investment.
So in general I would be happy if people used it as payment whenever possible.
I think it's the fact that companies accept bitcoin as a payment why bitcoin is the most important crypto currency. And I would like it to stay that way for a while.
Indeed it was created for payment purposes, but it was definitely not to be limited for only payment purposes. Over a period it evolved and people used it very well. We live in a progressive time and have to evolve and we can't be stuck to old methods. Change is permanent, so I feel people should not stress whether it's yet investment or payment. People are smart enough to decide so let's keep it that way.
exactly because bitcoin was meant for payment purposes we have to store it!
because simply you can take a look around and see that there is not enough places where you can spend bitcoin, it is not yet accepted by the merchants which makes it hard to spend but easy to store and take the profit.
