Not really... Many Tor users use cryptocurrencies. Many cryptocurrency users have little clue as to the extremely limited privacy most cryptocurrencies offer. This makes it an important topic of awareness for Tor users on tor-talk. The continuous attacks and analysis upon the blockchains by dataminers, marketers, lawful and unlawful government agencies including law enforcement, taxation, NSA style GPA / GAA / parallel construction, questionable untested new "laws", corporations, status quo anti-adoption efforts, internet censors, DPI filters, researchers, even other users... all around the world... is at least on the same level as that against anonymous overlays like tor, and even clearnet itself. Most of the cryptocurrencies out there... - don't use TLS, thus their entire networks have zero privacy / auth / integrity over the end to end transport - don't use internal cryptoprivacy to protect transaction info - don't have communities much aware of or using overlay networks, out of band comms, encryption - don't really care much about privacy in the currency itself - don't have clients that directly support, or services that reside on, overlay networks. This includes exchanges, miners and mining pools, relays / nodes, payment gateways, forums, wallets, DAOs, etc. So if you're a tor user for reasons, and want a cryptocurrency that demonstrates similar reasons / capabilities, your choices are limited. And there's a lot of lingering 'cryptocurrency is private' promotion from earlier days left to dispel and to re-evaluate. If you want to follow / try / contribute to some recent developments in stronger cryptocurrency privacy search out - privacy coins - decentralized exchanges - even older forms might be noted / useful such as... coin mixes, blenders, swaps, joinmarket, etc Examples... Zcash ZEC, BitcoinPrivate BTCP, Monero XMR, Zencash ZEN (uses TLS), Bisq exchange, etc Though evaluating them might be off topic, since tor users are likely to have interest in cryptocurrency privacy feel free to list / link more cons / services / evals that you find in this thread for reference. BitcoinCash BCH might adopt something soonish, as may some of the other leading cryptocurrencies, check their respective roadmaps. Bitcoin (Legacy) BTC not likely anytime soon.
