Anyone can determine Bitcoin's future path by participating in a decentralized network without third-parties. How can people say Bitcoin is a scam this way? This is nothing more than an attempt to spread FUD in order to stifle Bitcoin's mainstream adoption. Believe me, those who say Bitcoin is a scam don't truly know what it's all about. Either they hate Bitcoin or simply don't understand how it works. Bitcoin's been doing fine even with mainstream criticism, largely because of its decentralized and censorship-resistant nature. As long as Bitcoin stays true to its roots, nothing else matters. Just my thoughts

Well, it's all semantics if you want to call decentralisation a scam. And depending on your intentions and what you hope to gain from it, with implementation still in infancy and much to improve in many areas, like all experiments, social, mathematical, ideological, financial, it may or it may not work. If a scam in its simplest terms mean that BTC goes to zero, or in a more complex way, its creators never meant for it to succeed, then all these possibilities aren't non-existent. We all can believe what we want, but that doesn't make any possibility any more, or less, real.
