Give BTC a little credit, it's capable of giving you a solid rush and getting you(r bank balance) high. It doesn't always bankrupt you. That's a lot better than you can say of krokodil.
At the same time, in some weird massive cognitive dissonance, anytime one of these evil governments they hate so much decides to legitimize bitcoin in some way by recognizing it as some financial instrument or when USD/BTC rises (and let's remember - dollars are a fiat currency a.k.a. useless pieces of paper that bankers print and force people to use) they are giddy as hell.
I even seen comments saying that Satoshi becoming instant billionaire (richest in the world by far, in pure currency, not 'net worth' that's hard to liquidate and spend) if bitcoin really became global currency is deserved for his contribution to humanity. Can you imagine someone saying Dennis Ritchie should own 5% to 10% for his contributions to Unix, C, etc. (that largely went unrewarded and he died the same time Jesus of electronics Steve Jobs did so no one even cared). Or RMS for the FSF? I just can't imagine how much you have to like a thing (FOSS, Unix, C, Bitcoin, ..) to say its creator should be rewarded that heavily and become the richest person in Earth's history.
The life expectancy of a user is 1-2 years as their tissue starts to die.
I think it's an apt comparison of the 'potence' of these two things. People who take coke don't rot alive and die within a few years. Similarly penny stocks are (relatively) harmless, never used to buy illegal stuff and people who do them don't go around saying that penny stocks will replace all finances and currencies and cause a revolution against the corrupt banker filled governments and accuse everyone of being governmental propagandists (yada, yada..), many of Bitcoin proponents on the other hand...
