Bitcoin is very much useful,i think it is future currency.bitcoin is not handling by any government.this is decentralized also.it is very useful to fast and secure transactions.bitcoin is more profitable to investors,it is very useful to this internet world.according to my view many people love this bitcoins.
That is true! I dont think so bitcoins are useless in any way. There are innumerable advantages of using bitcoins, then how one can call them useless. That would be really unjust to bitcoins services. Bitcoins are decentralized, highly transparent, offer easy transactions etc. what else one need. Bitcoins are the future currency of world.
I think blind crypto-optimism actually hurts Bitcoin community, the thought that Bitcoin is perfect and soon all of humanity will open their eyes and adopt it is so naive. People don't massively use Bitcoin because current fiat systems work just fine for them, most people don't understand the benefits of decentralization and immutability, and even those who do decide that the costs of using Bitcoin in terms of fees and volatility are outweighing those benefits. In order for Bitcoin to become the world currency, it must become better than fiat in all aspects.
