The fact is that everyone is entitled to their own opinion, that they call Bitcoin a ponzi scheme doesn't change any thing about the originality of Bitcoin. Such people have little knowledge about how the Blockchain technology works, they need to be enlightened
Yes. Indeed because of a wrong using of bitcoin it entitlex that its not because bitcoin is crypto and it is decentralized they can used it in their illegal activities. It can be a big effect in the crypto world and the inocent will involve too though they did not do any illegal activities. Its sad to hear that because instead of helping to support bitcoin to legalized it we are also the reason to destroy it.
for me it's just an expression of someone who hates cryptocurrency or bitcoin so we don't need to ignore them, but in doing so can make dimarket prices turn down but won't have a big impact.
