All alts suffer as bitcoin begins to rise. Isn't that always how it's been?
Most alts spend >90% of their lives falling against bitcoin and <10% of their lives rising against bitcoin.

http://www.cryptocoincharts.info/pair/xrp/btc/poloniex/alltimeXMR:
http://www.cryptocoincharts.info/pair/xmr/btc/poloniex/alltimeXRP is non-proof of work and shows the same ratio. XMR is post-Gox coin and shows the same ratio. This ratio is common to all altcoins regardless of their individual characteristics and regardless of time.
Therefore, we as altcoin investors must get used to the idea that we will spend 90% of our time watching our money shrink and 10% of our time watching it explode.
My hypothesis is that the transition to the next XMR bull market will be sudden, not gradual. People will be wondering whether XMR is dead in one moment; in the next, it will be rocketing to .01 per bitcoin or beyond.
