Holding BTC for longterm would be the wise idea, however better to take small profits at frequent intervals.

btc would still have storage value, even if it doesnt make it to global lead currency

how can you sleep well then watching eth-rise and icos :)?

What are you doing with the proceeds of your sales? Are you converting to fiat? Or are you keeping them as BTC? I am keeping most of the profits I pulled out as BTC and investing mall amounts in low market cap junior coins I perceive as undervalued like DAR, XBY, BLK, BSD.

holding is the right option!
