Well some people may see bitcoin no more than a scam and it might still have problems as hackers try to destroy it but look at the bright side, bitcoin's price is increasing everyday and the majority of people are changing their mind about this cryptocurrency so why don't have faith in it. It's worth a try

Ya just like you said,many people said bitcoin is useless and scam especially because of black market site in deepweb.Last 3 year before price for bitcoin is rising,one of my friend said that.And today,see what happen,bitcoin price is more higher than us dollar.
