I had arguments with my friends who are always tagging bitcoin with negativity. Today, we argued and I educated them on bitcoin and Ponzi scheme. To me Ponzi scheme is when developers takes money from new entrance to pay early birds,rinse and repeat until they raise enough and vanish. But bitcoin is not like that. Do you think I am right?
Yes.
Bitcoin fees are high. Bitcoin is not used for transferring money. There are no projects about bitcoin. İts price only rises when there are more buyers, so It acts like a Ponzi scheme nowsadays.
i agree to that sir, the essence of being a currency is slowly fading away specially in micropayments its too expensive to transact to it, however many believed that bitcoin now is mre of an asset a store of value that appreciates over time, and to those that believed it was a ponzi the should do more research 
.. well just hope the lightning network will be widely and perfectly implemented specially at this times..For small transactions we can use AltCoins at this moment. Bitcoin is under constant development, today the network can be overloaded, but with an improvement the situation can be solved (at least temporarily, like it already happened), so the fees will decrease again.
Anyway, it's not a reason to consider Bitcoin a Ponzi scheme. No one will be scammed here. There isn't a central authority holding everyone's money and ready to run away on the first opportunity. The free market regulates itself, we regulate ourselves and we must be aware our only guarantee of success is to keep Bitcoin reputable, so the demand and the supply will be balanced and the currency will be usable. On the contrary shulio says, there are several projects about Bitcoin and people are still transfering Bitcoins (otherwise fees would be cheap).
