I just tried calculating my average btc buy price, it is not higher than $260 - probably around $230 - too many small buy ins to accurately calculate my average - I only bought as I needed them for arbitrage and trading.
I started with btc in may 2014 and have been actively arbitraging - I slowly purchased however many I needed for my activities from $440->$650->$275
I recently made purchases and tripled my btc holdings during the price manipulation crash - averaged a third of current holding through purchases from $300-170 and decided to call the bottom at $165 at which I bought a third of my current holdings -
first time I have more coins than I need for my arbitrage/trade activities - I am now part of the hodler crew for 2/3 of my BTC since I dont need them for my trading/arbitrage

TIP + ADVICE FOR ANYONE WHO DEALS WITH BITCOINS:
GET A TREZOR!!! I'm going to buy my 2nd trezor when BTC hits $300 and my 3rd at $400 - or I might just buy the party pack XD
