Should i specialize as "Attorney" for Bitcoin/crypto/icos/blockchain?

So basically i am just asking if there is somebody who provides legal input on Bitcoin/cryptocurrency/blockchain/ICOs and so on. Is it worth it. Is this the niche one should specialize in. Is it already too late?

I am not asking for myself, but for a friend who has studied law in university and basically isn't doing anything with it now. I think that specializing in these "Crypto" things could be VERY beneficial, especially for someone who is earning currently 25k$/year(Although it comes with a normal care-free life, social care,no stress, easy working hours.yeah that's europe..).

Could someone provide their input? Am i wrong, or should i help that person and tell them to get into these things as they could pay off very well? Anyone who is providing legal input on these things, maybe share your experience?
