Just because I don't understand certain terms, should not be enough reason to call me or anyone dumb. Remember that Bitcoin is still A Peer-to-Peer Electronic Cash System, and cash system are meant to be simple for use.
Some people are dumb and might not be able to learn certain things.
Sure they might have areas in which they are smart, but the fact of the matter is that some people are dumb and they stay dumb in part through their own lack of efforts.. and surely there could be some who are dumb through genetics rather than environment.
I do like to attempt to give people the benefit of the doubt regarding readiness, willingness and ableness to learn, but sometimes there are people who don't want to learn new things and/or might even be hostile towards learning certain things, and technology related matters frequently can bring out those kinds of purposeful expressions of some folks saying that they don't want to learn certain things.
This is an important point you are bringing up and as I am someone who likes reading JayJuanGee's posts, I am convinced I understand how he means the word dumb. It is not an ad hominem attack, it is a description of how much knowledge a person is either capable of or willing to accumulate about a certain topic. It sounds like an insult to those who take that word out of the contexts that JayJuanGee stands for.
But let me chime in here: I can say for sure that I have been approached by people who asked me how to buy bitcoin and how to store it. I knew that some of them intended to make very small investments, which means fees would tremendously impact them, and some of them just didn't have the capacity to get into self-custody
properly! Self-custody is not superior per se. You can mess it up. People do mess it up all the time. Knowledgeable people messed it up in the past and will mess it up in the future, may it be accidentally (which it mostly is as nobody does it on purpose).
My recommendation for those people is to pay attention to what exchange they choose to store their bitcoin until they feel the time has come when the risk to keep it on an exchange outweighs the risk to get self-custody organized somehow. There are huge differences in the exchanges one can choose. I know that FTX has crashed and even professional institutional investors lost money and so on. But still, if someone goes with Coinbase, for instance, chances are pretty low that they can mess up things the same way FTX could do it. There are exchanges where the risk to store a certain amount of value is relatively lower compared to other exchanges.
