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.
Showing to random people that you are holding very large amounts of cryptos is not safe, because they can try to scam, to steal or to extort you. In addition, it would be very hard to find several specialists of the matter to hire. How and where he could find them? If he places an advert here or on social medias, do you really think he will get serious candidates? Maybe he can try to look at
Wizard of Vegas or at some specialized subreddits for example, but meanwhile it's not a bad idea to ask for insights to the community here.
On this board the OP makes the same. He shares his information to unknown people. And he can get the information he can`t believe - no one will take responsibility for bad advice. When you have really big money, you have information about various specialists and you know somebody who can search information for you. As i said, a know few men with really big sums in crypticurrencies - no one of them know about this board.
