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 
Bitcoin is not a scamming currency/investment and I think that it can become a very big currency to be honest, its just how you also look at it of course.
