Although it's a nice thing to do as an investor to check the Bitcoin price, for someone who is ready to invest in bitcoin for a long period of time, the current price of bitcoin is not an issue. Because we still expect the bitcoin price to be higher than the current price as we are now thinking of the bull run soon, you can see that as far as he is ready to invest, even if it's a little amount, he can do that for now because he is still a newbie and he may see the price and feel discouraged when he sees that he won't be able to get much btc with funds in his hand. However, he shouldn't mind the price right now; he will definitely get his money back and profit if he is able to endure the risk and can hold for a long period of time.
I didn't get you correctly with what you meant when you said that he should find a professional investor; did you imply that he should find someone more educated about cryptocurrencies than he is to handle his investments? If that's what you mean, I don't believe it's appropriate for him to date. However, he is capable of doing it for himself through his commitment to the cryptocurrency industry; if he makes an effort, he will invest the money himself because it is not difficult.
