There are a lot of folks who continue to be skeptical and scared of bitcoin, which will likely be their loss, and there might not be any real easy way to either convince them and/or to get them to take action to protect their own finances, psychology and likely improve their future options. Even people who we might try to help, they may start out buying bitcoin, but then screw it up and even put themselves into a worse position because they fail to adequately prepare themselves and to learn about bitcoin and/or to moderate their entrance into bitcoin.
You’re absolutely right, there are people who are very ignorant of themselves, and lack that decision making, probably because of some bad experiences that they may have had because of some dealings with shitcoins which have been a very bad experience for them, well it will most likely be their loss, some might have a way to be convinced while some might not be able to convince, I know of a certain guy who we were close when I started investing in bitcoin, he was quite lackadaisical because he has previously invested in some shitcoins because he was looking for a quick profits, not knowing that he was loosing money, he invested in a shitcoin and lost sole like huge amounts of money, so when he hears about cryptocurrency he is always skeptical, so I was actually able to convince him that bitcoin is different from this other shitcoin, he keeps asking about my investments in bitcoin when I started, so he realized that bitcoin is different from all that shitcoin, he is eager to invest when he has a discretionary income and continues accumulating consistently.
Hope you also advise your friend that Bitcoin can also be volatile and sometimes their is a dip which affect the price, and he shouldn't panic whenever he witnesses something of that nature with his Bitcoin, because in most cases people just want to talk about how awesome is it to invest in Bitcoin and they sometimes forget to give a balanced analysis about the fact that the market is prone to fluctuation, which in most cases is temporary and the market will correct itself with time. Hence you give him balance analysis, he will not have to think and reflect about those shitcoins he once invested if a dip occurs.
