So some people argue the switch to POS will be end of 2015 and others are saying mid 2016. There are good arguments on both sides. I don't know but I would bet end 2016.
Do we need a vote to settle this once and for all?..
I don't gamble, or trust any prediction market service either , but think your expectations are extremely "optimistic".
Bitcoin will either never change to PoS or such a change won't occur till 2024 and beyond.
I suggest you gamble all you want with PoS. Seem like you are a Nxt proponent.... that currency is dying right now if you haven't noticed. Dropped from spot 5 to 8 in market cap and soon to be overtaken by Bitcoin assets like Counterparty! Ethereum, Counterparty and possibly Storj will likely overtake Nxt in 2016, expect it will drop further in market cap.
