Bitcoin is a Ponzi scheme, investment scam, and only used for illegal purposes only.
Back then it is what most people think about Bitcoin specially those who doesn't really know anything about cryptocurrency, most of the time the negative comments comes from those who doesn't really know a thing about it.
Bitcoin haters is still pushing that narrative of calling Bitcoin Ponzi scheme because of their involvement in pump and dump coins and the wrong rumors that was falsely going round by Bitcoin haters but the majority of those they had been involved in criticizing Bitcoin investors has been confirmed to be those that has never been involved nor investment their Penny in Bitcoin yet they believe that Bitcoin is a Ponzi scheme.
There's only 3 types of those haters/bashers/critics.
1. They have been involved with some ponzi scams like doublers,hyip's, some Bitcoin fraud investments
2. They do just simply go on what other those other bashers say without even knowing on what they are bashing into.
3. Bashing out Bitcoin/Crypto but secretly they are just that making out some investment behind the curtain.
We have those common dumb arguments such as this and its been long time that those labels being thrown out to Bitcoin or crypto as a whole that this is some shit scam and since this is their first time on hearing out
then they would be having those doubts about it and just going in together with other people. For those who had been known or having that experience or totally knowledgeable about Bitcoin or crypto then you will be seeing these stuffs to be that laughable. Sooner or later these people will be able to learn up the truth and will be seeing themselves that they should have known this earlier and be able to ride up at least.
