I don`t think that it is a problem to hire a specialist that can find several advisers in cryptocurrencies and compare their information. In such way the OP will get combined advice from the several persons and he have a real man that made it. So he has a man with the face but not unknown nicknames like here. And the same time i don`t see any problem with cryptocurrencies convert. If the OP has his money in cryptocurrencies - he need to convert a small part of them to pay a consultant or he can pay him in cryptocurrencies too.
