Lol, good one. 

Things change with time, and so do people's perspectives on things. I remember the time when the mainstream media used to call Bitcoin a bubble and used to say that it's going to pop one day and everyone investing in it will regret their decision because it's like a ponzi scheme and investors coming later will lose money eventually, but they were all proved wrong, and those who were investing back then must be swimming in profits if they held onto their assets from back then, and I bet every single person that thought of Bitcoin negatively back in the day is regretting it badly to this day seeing Bitcoin's popularity and value.

The same thing is going to happen with those who are calling Bitcoin a scam even today, and I really feel pity for them because they are still aren't able to see the reality even though Bitcoin has proved itself in front of the whole world and even the industrialists and billionaires are now into Bitcoin because they have realized the potential it has for the future.
