It's so funny that at this stage and century , some people still believe that Bitcoin is a scam after it has proven itself over and over which has led to it's massive adoption.
We can't avoid people thinks Bitcoin is a scam, they can hardly differentiate a company exploiting Bitcoin for their scammy agenda and the native Bitcoin blockchain system. Many newbies especially those who relies on other peoples information without verifying the fact behind it are often subjected to this kind of idea until they do a research themselves and discover that they have been fooled by these scammy propaganda of people that they had trusted.
There are so many things these peoples must understand to know why they are really a slave to the fiat system.
Not necessarily a slave of the fiat system, probably because these people got swindled by a company pretending to be a Bitcoin company. We had a lot of experiences like these in the history of cryptocurrency scams.
In short, due to the short-sightedness of people and being too lazy to know the actual fact, many are misled to believe that Bitcoin is a scam especially those who idolize known people who are against Bitcoin like Warren Buffett.
