Most people seem to be either day trades or hodlers. I personally don't know that many people that buy things with it because they believe it's value might skyrocket based on historical data. If that's the case, might that be Bitcoins biggest downfall as a currency? I'm no economist, but that seems like a big long-term pitfall to me.
Many peoples believe bitcoin is store of value or digital gold. People buying bitcoin because they believe bitcoin will be good investment for long term. Bitcoin can not replace national currency because bitcoin is decentralized cryptocurrency and i think bitcoin is like an asset or store of value
