I can see how someone uneducated could arrive at the analogy of a lottery ticket, because there are significant of people out there who buy Bitcoin purely in the hope of becoming wealthy. There's no denying some people are clearly using Bitcoin for that intent. But, as others have pointed out, it's downright disheartening that an educator, of all people, could arrive at such a simplistic and banal conclusion, particularly when even a hint of understanding would lead you to recognise that's not what Bitcoin is.
It's like when people say the internet is just people sharing cat videos. Congratulations on your pedestrian surface observations, which technically aren't incorrect. Lots of people are using the internet to do that. Oddly enough, though, there's a little more to it than that. See the bigger picture, perhaps?
I would rather say that Bitcoin is a Ponzi scheme is much better than Bitcoin is just like a Lottery ticket. I don't know why he do get those analysis yet same as you said
those are just like f*ckin pedestrian surface observations and didn't even tend to go deeper and to know more on how Bitcoin works and its true usage and I do even believe
that he do made such line by just having a single glimpse on BTC and didn't tend to looked once again.
