Usually an old people is lazy enough to learn alone, they will ask their child or someone is younger then them to teach and guide them. So I think a video tutorials doesn't really help them, most likely they wouldn't watch it and will say it's hard or give other excuses. Traditional casino is more preferable for old people because they've experienced it and know how to play. Maybe this is why traditional casino is still alive until now, I believe when the new generation already get older, traditional casino might not be successful like now.
Yes, you are right. most of the elderly prefer to be told directly, rather than having to learn through tutorials provided by casino platforms or from various other sources. most of the elderly, would rather ask someone close to him to teach him about something related to technology. and the most effective is to teach them directly, and even then step by step, if not, in a short time they will quickly forget.
So, crypto casino feature for elderly will not be effective. why, because I had a similar experience as the OP described in this thread. at least, it took some time for them to memorize it properly. Regardless of all that, associated with traditional casinos or land casinos. I'm pretty sure, however, land-based casinos have their own advantages over online casinos. Traditional casinos will still be loved, not only for the elderly. especially if the casino destinations are in big cities, such as Las Vegas, Macau, Marina Bay Sands. at least, there are many gamblers around the world who want to visit big-name land-based casinos as vacation destinations.
