As long as I am certain, I know that bitcoin has long grown pass the stage of skepticism (whether or not it is a scam). Bitcoin has vindicated itself several times amidst all kinds of allegations of it being scam or some kind of Ponzi schemes. Maybe what people should be asking or considering is how long bitcoin is going to last. Whether bitcoin will be in existence as long as internet is functional or it will be defeated by the government one day.

What you call the biggest fraud happens now with bitcoin also. Many people in different countries pay hugely in the name of cryptocurrency tax. The government of many countries have discovered how to successfully task bitcoin or crypto earnings.
