Barely! The ruble is down 50% YTD and Bitcoin is down 54%. But also consider that in 2013 the Ruble went down 6% and Bitcoin went up 800%.

That's actually even more distressing. You want stability out of a currency, not wild swings.

Indeed, but keep in mind they are talking about investment, not currency. Wild swings are great for investment, as long as it swings up eventually.

Even in terms of investment, you want steady, constant growth... not unpredictable swings.

As of yesterday, when the article was written, maybe. The ruble has dropped another ~10% in the past 24 hours.

Don't worry, before the end of year, rouble will probably be 66% down against dollar!

That's a misleading comment. Sure, if you bought BTC on January 1st, 2014, maybe, since this would have been timed perfectly to align with the peak of the Bitcoin bubble.

But if you bought BTC only 60 days earlier (November 1st, 2013), it was at $200, so you would have a +65% return rate as of today, easily beating the ruble, or virtually any of the world's currencies for that matter: http://bitcoincharts.com/charts/bitstampUSD#rg60zigDailyzczs...
