Yes definitely don't leave any coins laying around on the exchange, the security risk is way too high. When we recommend it teach somebody about bitcoin and other crypto coins it's important that we make them aware of the security risks. There have been big scandals in the past and it's up to all of us to not repeat the same mistakes again. In my family only one person is holding also crypto currencies, my cousin. Last year for his birthday I made a small crypto portfolio for him to store his coins. He hasn't really bought any by himself, but I am going gift him some again this year for his birthday. Among my friends it's a bit different, I would say that 60-70% own a few bitcoins but aren't really using them for purchases. Because I kept talking so much about cryptos they all wanted to get invested as long term investment that might pay off in a few years. Only one of my friends trades still in CSGO skins and uses bitcoin for that.
I also finally managed to see my cousin yesterday, now I have to work a lot in the evening and at night, so I am almost constantly busy, and it’s very tight with free time, but yesterday we saw each other and I shared with him that I was buying bitcoin. He said that he had already heard about bitcoin more than once before, but did not attach any importance to it, however, like I once did. It seems that he was interested, I promised to help him if he wants to buy.
