Btc is cup money is liquid the water and Banks are from the word like a River bank.
So money currency is water and btc IS the cup all assets gold btc and other crypto are the cups where the money the water flowing in.
Those who got cups to collect the water when it's raining those got most of the water so to speak they got most of the money.
If u sell btc early it means you empty your cup ...btc is big cup small coins smaller cups they full faster then biggest cup the bitcoin.
Those who got cups when its raining they collect the most of the money more water more cups needed to collect water.
I mean in my opinion it wasn't a great thing to teach Bitcoin to someone that wasn't really interested, the only best way to learn Bitcoin is to learn Bitcoin on their own and have their own interpretation of it, and there are going to get that if they already have knowledge on there own and experience it already. I've heard a lot of stories where they tried to teach Bitcoin to their friends and it wasn't really effective, and some are just going to blame you because they lose money on their investment in cryptocurrency. This was all a pretty normal thing that is going to happen if you just encourage them and they are not really interested in it they are just interested in the profit.
The thing is you just need to explain the basics something like here is Bitcoin, it's a digital currency blah blah, and then say something like try to take a look at it and see if you're going to like it. Because in the end if they really wanted to invest on go into Bitcoin and cryptocurrency they need to do it on there own anyway.
