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.
Three people exist says that.
One is those complete newbie which crying for their losses on bearish condition and think about bitcoin is scam due to that matters.
There are also people who knows about bitcoin but they hate it its because they have other favorite coin that they support and saying something negative is their way to shift the attention of people and try to see their project and gain a new investor that will support them.
And last are those institutional investors who want to manipulate on the minds of people, they play mind games so they can influence people to do action that they like and they always get benefit if they can influence people either to have panic and sell their bitcoin or either they want to FOMO them and convince to buy.
