Bitcoin is burning down. Basic lesson in investing : If the public can't explain what the investment is, does, and how it makes a profit, then it's a bubble (scam).
Bitcoin isn't a currency. It creates no product for sale. It has no employees. It isn't a business.
Anyone who bought in to it deserves what's coming. It's only purpose is to make transactions, mostly on the black market for drugs, guns, CP, prostitution, and laundering. Regardless of the small inroads it made in legitimate business, it's not an investment.
Hopefully the smart people cashed out at the right time.
