this is the reality of so many persons as they try to think that bitcoin is just like any other cryptocurrencies. And I think it might be as a result of the ban on bitcoin by government of different countries and because of this, people would want to shift into other cryptocurrencies just to be on a safer side but with the so many coin on advertised on YouTube and sent as ads when you search for bitcoin and crypto related stuff, it is very possible that so many person might have invested in so many irrelevant coin and might even hodl it hoping for a good return in the years to come.
Someone who is unfamiliar with bitcoin must of course have a companion in studying Bitcoin and he can also learn while investing in Bitcoin. Maybe for now there is enough education about Bitcoin that they can learn so that there is nothing that makes them have to turn away from Bitcoin. They can start with a smaller investment considering they are still in the learning stage and the best option is of course to do DCA regularly with a value of $10 for every purchase they make.
Yes, everyone has had quite bad experiences in their past, but they can improve on those experiences to learn from their mistakes. For that reason, I don't think there's anything wrong with giving advice about the correct investment method for them in preparing a long-term plan.
