This is great to hear. Kudos to your friend who introduced you to Bitcoin. He is definitely someone you should keep forever because not many friends are willing to tell you the source of their income and even have the patience to guide you through it. It’s also a good thing that you listened to the advices you were given because it takes almost nothing to lose money.
I agree, and furthermore, it wasn't just a friend who helped me get acquainted with Bitcoin, but also someone who gave me many other pieces of advice. We met in the hospital when he was recovering from a serious car accident, and I was hospitalized for a planned scoliosis surgery. As you can imagine, it wasn't exactly an ideal situation for getting to know each other, and yet, despite everything, I consider it a great encounter in the end and am grateful for it.
