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 dont know fully about bitcoin and their market out there but i believe people start to realize this is one of the best investment nad then trying to tell any people out there to invest and make it stronger or bigger. But when people who tell the story take his money out see the market goes down. At the moment i think btc is the biggest multi level marketing #imho
