Some people think bitcoin is a bubble, for me it's not.
They just don't understand that what makes bitcoin unique from another type of investment is because bitcoin is decentralized and with a fixed supply.
Hence, the price is very volatile, and we know the reason behind, it's the manipulation by the whales but it will not make bitcoin worthless even if it will dump in the long run as we know bitcoin will recover as well.
Bitcoin is not similar to a Ponzi scheme, it's an investment that does not promise anything.
The lack of financial education really hurts people in scenarios like this one, bitcoin is not a bubble but bitcoin like any other asset can be subject to form bubbles from time to time, for most people there is no difference between those two statements but for us that is all the difference in the world.
Bitcoin has been the best performing since it was created, you cannot maintain that kind of performance if it was simply a bubble, bitcoin is very volatile but that has to do with its small size compared to other financial assets and due to its inelastic supply, this creates bubbles from time to time but nothing that anyone that is willing to be invested in bitcoin for the long term should be worried about.
