That's why privacy coins are important. Privacy and private property is a measurement of civilization. Komodo supports decentralized private ICOs. Zcash even had praise from Snowden. So that's a very big green flag. PIVX was the first and only PoS coin to implement Zerocoin protocol. I'm personally very impressed with zk-SNARK tech (including the cool sounding meaning of the acronym)

Dash has trustless mixing which has still unbroken privacy which they keep on improving with 4+ million USD per month budget.

Monero is not something I'm willing to trust after their privacy got completely and utterly broken. They claim they've fixed and it's probably true. But the track record of the team isn't so bright.

Verge(XVG) seem pretty impressive and I'm positive about the project. But I don't think I've done enough research to make a claim about the coin.

Hope the info was helpful :-)
