Enthusiasm for novelty, however, can be damaging. There are reports from financial institutions, such as the European Central Bank, that show that Bitcoin has many points in common with pyramid schemes, otherwise known as "multilevel marketing." You see, we're not talking about buying Bitcoin the same as investing in TelexFree, but you have to be aware that Bitcoin is still a developing currency with no government control. So you need to be aware that various problems can happen, such as thefts or who knows a sharp devaluation of the currency, which can lead to financial losses for those who wanted to use Bitcoins as a form of investment.
Only invest what you can afford to lose. Bitcoin can be a large pyramid scheme but who knows? All zero-sum market can be looked as a pyramid scam but we can't disprove it and at the same time, we cannot prove that bitcoin isn't a pyramid scam. The only good thing about bitcoins is that you can exit anytime you want. If you're thinking that this is a pyramid scam and it's bothering you, you can save yourself by disposing all of your coins. You can't do this in a usual MLM. Once you joined, your money belongs to the pyramid and the only way for you to get out without loss it to refer someone and earn from the affiliate program.
People always ask questions that have can't be answered at all so it's no wonder why most of us are asking is "Bitcoin just a huge pyramid scam?"
