Not just you, I typically care little about alts because bitcoin is functionally "the reserve currency" of cryptos.

Dark is first to market with a feature much clamored for. Others may state "any coin can do that if they want", the fact is they aren't and by that logic bitcoin would be worthless because there are clones. First to market is key.

Dark also seems to have some competent organization behind it, which is rare.

The user base won't be just the drug world and pedo's, but people who are into crypto because they believe in the political promise. Built-in anonymity is a huge component in achieving these ends.

The government is useless to stop it, you're a fool if you fear the effects of a ban-hammer... the government can't even keep drugs out of prison.

Lastly, stupid and useless coins go places all the time, that should build confidence in a coin that actually has some utility over bitcoin.
