Somehow I see bitcoin as a useful currency to be used in banking transactions or processes. Though there are risks for its valuation or pricing but it really can be so helpful. The fear about bitcoin being used for illegal activities is really a common thing with actual money. So if we will be asking how different is bitcoin to the physical money in terms of usage for illegal activities? I think not at all. I think it is not even safe for them who use it for illegal activities because they could be traced through exchanges.
