Anything that goes up fast will come down fast. That simple is that. The sooner you sell your speculative investment the more likely you'll get your money back (at the expense of other people). I sold some leftover coins of mine after 2x in price and that's still phenomenal gains from just some random coins I saved for any next purchase.

The value of BTC will slowly rise but naively extrapolating from the last year or so only I'd say the realistic value is still below $100. I'm pretty confident that roughly $50 is a rather stable floor for the years coming.
