Whoever posted this quote bitcoin scam doesn't know what bitcoin is.
This is not necessarily true, there are also many people who are very knowledgeable about bitcoin but for some reason they don't like bitcoin and don't want people to like bitcoin so they spread lies about bitcoin. If we can learn bitcoin easily then so can others, don't look down on them just because they say wrong things about bitcoin. We need to find out what their real purpose is.
Just like many famous people in the past said bitcoin is a scam, bitcoin is only used for money laundering but so what, now they are one of the investors holding the majority of bitcoin. If I remember correctly, the CEOs of Blackrock and Microstrategy were also people who spoke ill of bitcoin in the past, and currently they are the ones who own the most bitcoin.
Actually it makes sense not to quickly judge them because we don’t know what they have been through. It could be a really bad loss. But despite that, it must have been a misunderstanding that caused them coming to that conclusion because you can’t blame Bitcoin if you didn’t have proper knowledge before investing. It could also be people who have been in a “Bitcoin” pyramid scheme. At the end of whatever reason it is, it’s a misunderstanding though.
