Giant ponzis do not run for more than 10 years. At $600,000,000,000 invested in Bitcoin the money supply has dried up. Bitcoin has crashed from $20,000 to $12,000
and high profile people calling Bitcoin a giant scam there is ever increasing risk of international police raiding Bitcoin mines
I think a $ 400 bitcoin is a nightmare that will never happen, even though bitcoin is down, but I think it will never touch $ 400. I do not know why you are too negative to bitcoin so make such predictions.
