Whereever there is a pump, people don't care much about what they are buying. As long as they have that feeling of getting rich quick overnight and until they are buying in. At least this is what majority of people do. BTC can be used as a currency but mostly it is used for trading and for flipping money with other altcoins etc. Of course all of them are correct. Everybody should have the right to believe in what they want, it is their choices in life..
