I have never recommended on purpose crypto or any other casino offline. I think that I should not bother others with gambling. If someone asks me for an advice where to gamble (while it strange to get such a question, as people look for any answer first in google nowadays), then I think I would name some popular casinos. But I will try to avoid such question, as I feel like I dont want to talk much about gambling offline, as I would feel responsible for that. One thing if you just show something gambling related and unintentionally recommend that (like signature), which means you dont insist on that. And the other thing is that you on purpose send someone to a casino.
I agree with you. I don't recommend specific cryptocurrency casinos to anyone unless they ask me about it. I once had an acquaintance interested in cryptocurrency casinos and I briefly explained to him what cryptocurrencies are and how to use them. I saw in his eyes that he was not interested even before our conversation came to cryptocurrency casinos. As he said, it's too complicated for someone who has never used cryptocurrencies. Those who use cryptocurrencies are able to find all the necessary information about cryptocurrency casinos on their own.
