In the first place,the truth is,many people are myopic on what bitcoin is all about.The same thing happened in the early days of internet,meaning many people didn't anticipate the problems internet is created to solve ,and the same thing is applicable to bitcoin.
However,many people have not been educated,enlighten, sensitize,and taught how bitcoin will gibe them financial freedom ,and this is one of the reasons people are condemning bitcoin.On the other hand ,many people have not understand that bitcoin can't be printed anyhow like some traditional central bank are printing and flooding the economy with traditional currency of which the ecovonmy will be in shamble in relation to the currencies being printed.On the other hand, some elites residing in some countries are advising and telling their people the risk of buying bitcoin,and this has resulted in people condemning bitcoin.
