Soothsayer
I am very time short so I'll make this brief. Yes, there is volatility, but that will settle down and is indeed showing signs of settling to acceptable levels as the whole system becomes embraced by more organisations (and some governments). Bitcoin is at the beginning of the journey but is definitely here to stay.
I have a question...do you think that fiat currencies have real "value"? Then ponder this....The fact is that if everyone in the US wanted cash for the assets they hold then the government would fall short with the supply of money by a frightening amount (about US$10.5 trillion)..... AND that is the most stable and secure currency on the planet. If we accept that as a workable system then why not a decentralised system like Bitcoin??
As for the criminal element....this has been grossly exaggerated. There are plenty of shock-jock style articles about this but there is a fundamental problem with their numbers they use. If, as they argue, transactions are unidentifiable on the dark web and the like (therefore attractive to criminals)...then how have they established that it is actually criminal activity given the so-called untraceability? There is a bit of a paradox at play here.. FYI read

You think it's all a scam, I think that this technology is here to stay. Let's leave it at that!
