Hang on tight. Don't lose faith. This is time to buy up more coins while we go through this period of slow down.
but what if it goes down some more and wont go up for 10 - 15 years?
What if it goes up and never comes down? There are risks both ways.
Granted, being as bullish as I am, I always think "this might be the last time we see 70" and so on. But I do think there will be a day when the double digits, triple digits (and so on) are gone forever.
Actually, ideally, BTC will be around $1, like the Second Life currency L$. Then people will start using BTC as what it was meant to be - an anonymous currency!
(I should shoot myself for saying that, given that I haven't sold yet...)
