I have a friend who has been doing well

On the 1st, he asked me how to use the wallet, so I demonstrated it to him using 4. I bought 0.01B, and he said to buy 15U, saying that was all there was in the wallet. I told him to leave a little for transaction fees, and he ended up buying 10U. By the 3rd, he told me that his wallet showed 6860U and asked me what was going on. I could only act cool and said we were all getting rich. He asked me what to buy next. I said I thought the Binance Life coin was good and had a nice meaning, isn't it just the life of freedom you want? Let's buy it together, I went all in, you can do whatever you want, and in the end, I bought 0.01B while he really went all in with 6850U. This morning, I asked him, and he sent me a screenshot of 4110010U.
