What I like best about bitcoin is that it is anonymous that is a good thing but people use it for the wrong reasons.
Also do I like the low transactions cost compared to the banks, it is just so much cheaper.
Wrong reasons? It's a currency so people should be able to use it on anything they want good or bad. Without a black market bitcoin wouldnt be where it is today and even if it never gets adopted fully by the mainstream it will still have a use so good for everyone if we want bitcoin to retain its value and not collapse.
