Bitcoin is in a bubble. "Anonymity" itself is unfortunately a nice-to-have value, not a must-have. Its price might increase again, and then drop, but that doesn't change the fact that some cryptocurrencies are valuable only because of scarcity and price-optimism.

Some coins do add value; by utilising blockchain technology to actually generate value. Steem as we know is powered by its users. JSEcoin allows browsing without ads via browser mining (I love this idea!). SiaCoin allows you to lend your extra storage space. Those might gain value in the long term; but are not for daily traders.
