I pretty much think that bitcoin is a lot silillar to gold right now, much like gold people used to use it for transaction pay with it treat it like it is a currency but over time with the value increasing it become more of an investment that people rush to buy it and save it and wait for the time when it has a very high value so they can start profiting out of it.
Totally agree with that because the bitcoin now for me is sounds of "investment" because the bitcoin is still growing and as long as many are supporting the bitcoin in terms of buying it, it means that the bitcoin price will still grow so I think that is the reason sounds like investment for others or making money term.
