honestly cannot understand you.
it's not happening soon. it's not happening now. it will happen, but the way you're phrasing things makes it seem like it's right around the corner..................
dang..... better get out now.......
Think about it.
All of the currencies are mined to stuff and require expensive as hell setups to mine. The said setups require near sold out parts which hurts everyone when you buy the said parts out (graphics cards / power supplies / cheap processors), etc. The current situation is screaming a soon burst of the bubble, and denying that is very ignorant.
Just like the other major bubbles that popped throughout the years, including the video game crash and the .com one, all have similar symptoms that current digital currencies / coin is showing.
I am not saying that it's going to happen tomorrow, no one has said that. I am using "soon" in the sense of in the next year or two, it'll be bound to happen.
Do you understand now?
