Litecoin IS officially dead and the BitsharesX is rapidly catching up to it. BitsharesX is the most innovative cryptocurrency to date that is why it has risen so much over the last few days.
Hate to point out the terribly obvious, but I do believe if you are using coinmarketcap as a metric you might want to get the calculations correct. Unless I am very wrong in this, I highly doubt 2 billion coins are in circulation. Ergo the "market cap" looks more akin to Auroracoin holding back, what was it 90% of the market, and inflating values by restricting coins from the market yet coinmarketcap still counts them.
I guess at the end of the day coinmarketcap is a horrible metric to utilize.
Well the supply does get somewhat restricted due to bitUSD(and soon bitCNY) being asset backed that require some user owned BTSX to be held in the decentralised exchange as collateral. From what I understand anyway. So that does hold back some of the supply but it's not the same as Auroracoin intentionally doing so, money being used in the exchange is a central part of BTSX.
Right now the market cap is almost all coming from China so we don't really know exactly how it's going to play out.
