People seem to forget what Bitcoin truly stands for sometimes and its disheartening. Bitcoin is not a get rich scheme or even remotely close to that. Bitcoin is a promise for freedom that no other fiat currency can provide. It is something that will only succeed if people want it to succeed, and it benefits everyone who uses it. Tbh everyone that I see who calls it a ponzi scheme or something arbitrary just doesn't understand it. They look at Bitcoin like every other asset and forget that its completely different. People in countries in Africa can't economically compete with people in America, but Bitcoin changes that. It provides a currency that is amoral and benefits everyone equally. Don't be distracted by short term moves in price and instead be focused on the fundamentals. That's all that really matters.

Here's some articles elaborating on this if interested:
