wow, that's truly a conservative perspective for anyone looking at a cryptocurrency (CC) of any type
Btc just made 5yrs old some days ago, and it wasn't until about April or May of 2013 that any level of "legitimacy" was truly enjoyed by the CCs, so I really congratulate you on having a year+ perspective; but I assure you that that is well beyond reasonable expectations for anyone getting into such a highly dangerous, extremely young, and massively volatile market in 2014.
Then they shouldn't be in bitcoin to begin with. I bought in during May 2013 when it was still bouncing around from the April spike, it spent the next 2 or 3 months below my buy price. I expected it, just as I expected to lose what I put in. It's all about framing your expectations going in, and having a solid understanding of where the true value lies in crypto currencies, so you don't get rattled.
Ok, given your btc experience what was BTCs "true value" in Jan '14, what is it's true value today, and what do you expect it to be a year after you purchased it in May of 2014?
That will tell me what type of expectations you have for btc, and how your expectations square with the actual performance of the CC.
