My observations are that way. I think Bitcoin needs to reach larger quantities. Can use bitcoin in people who are not interested in technology?
Can people use the bitcoin in the profession group like tradesmen, teachers, housewives, firemen, butchers? Are we going to see the days that these people use bitcoin?
yes the day of cashless transaction had already started to dominate the world and along with the same cyber war had started and hacker and bad guys had started to exploit the security loopholes so in due course of time bitcoin would prove a better technology for cashless transaction because its technology is highly secure and there is very little or no chance that hacker and bad guys could hack and get access to other account and steal others bitcoin unless he/ she knows the private and public key for a particular account.
So in my view I would say that use of bitcoin is not limited to any person or any particular group of society and bitcoin could be use by all people throughout the world. from tradesmen, teacher, housewife, fireman, butcher everyone could use it but the main obstacles the will prove bitcoin worse is its transaction fees high is getting larger and larger day by day due to big players we common man also have to pay a high amount of transaction fees and thus it fails to meet our requirements in this regard otherwise any non technical guy who want to use bitcoin could use it provided that he could afford to pay the transaction fees.
