Whenever i think this thread can't get any more retarded it does. The fact that so many people using large amounts of money to buy/sell bitcoins that don't understand the concept of EV is mind-blowing.
Explain the bare essence then.
By EV, I expect you mean expected value?
I see various forms of dollar cost averaging going on with various expectations that Bitcoin will acquire some additional value based on taking market share from remittances, store of value, currencies and hedging against irresponsible monetary policies. There are other motivations and theories as well, including various forms of speculation on price direction based on charts and lines.
Any special perspective or insight you can drop upon us cave dwellers?
It could also be exposed value. The fact that so many people using seldom used, unexplained abbreviations in this thread, is mind-blowing.
