This is the key argument for people promoting Bitcoin: Look how where we were a few months ago and look where we are now. It is only going faster - you should join.
This means that these people have jumped out of an airplane with no parachute.
They are now halfway down and are telling their friends: Look how well this is working, and it is going faster and faster.
When you tell the people they are going to crash-land, they just tell you it is FUD and that in their experience things have been going great since they jumped out of the airplane.
I hope you see the irony in ranting about how people talk about Bitcoin on the pure basis of sentiment, with no foundational reasoning to the argument. It would make sense that you appear to think that is the key argument for Bitcoin if you cannot also think beyond that. One side spreads FUD, One side spreads FOMO. You're part and parcel of the problem you seem to see only on one side.
Change your crowd and your sources of news and info. Spend more time in this forum outside speculation and economy threads. Don't miss the point of Bitcoin.
