Has BTC lost it's 'mojo'? Market dominance at all time low

Here is the BTC market dominance over the last year from coinmarketcap, we see that BTC started off 2017 with ~86% of the total crypto marketcap. The king of the crop...

By the end of the year, it dropped to ~34%, an all time low. You can see the other top coins/tokens under BTC (In Orange) rising in value.

Looking closer at a 3 month chart and with Ripple (In blue) and all of the 'alt' coins (In silver), it is apparent that these 2 were on the rise in the 2nd week of December. While BTC was on a correction to the downside, Ripple and certain 'alt' coins were on the rise. (Some of the sellers of BTC were purchasing the 'alt' coins and Ripple)

The marketcap for the 'alt' coins started 2017 at ~2.5 billion.

By the end of the year, the 'alt' coin marketcap was ~488 billion. An increase of 485 BILLION!!!

With $$$ going into the 'alt' coins/tokens, some of the speculators/investors are betting that there is more upside potential in specific 'alt' market compared to BTC going forward.

Has BTC lost it's luster as the crypto king?
Will it eventually be overtaken by,,,,,,,,,,,,,,,,,,,,,ETH or XRP???

Rodger Ver tweeted this chart a few days ago comparing BTC to BCH. So he apparently see's BCH as the 2nd generation with the latest software improvements.

Also, the IRS has stated that they have been tracking BTC transactions with the help of a company named Chainalysis. So some (In the U.S.) may be purchasing coins/tokens that are untraceable back to their wallets.

There already has been a move into various anonymous cryptos including Monero, Zcash, Dash, Zcoin, Komodo, Pivx, Nav, Zencash, Verge. I think this trend will continue going into 2018.

While I do not think the price appreciation in BTC will slow down significantly, I do think that certain 'alt' coins/tokens will continue to gain ground and will surpass the yearly gains going forward. I also think most of the 'alt' coins will disappear in X amount of years just like the fake dot com companies.
