A friend of mine is not interested in buying Bitcoin even after learning about it.
Because according to him Bitcoin is a small number of people who have a lot of Bitcoin. They can easily go down on the bitcoin market if they want to.
Example: Cz. Craig wright & Michel Sailor etc.
Looking forward to the well thought out opinion of the experienced in this regard.
Please tell me you didn;t expect everyone to buy the idea. If not, you need to be aware that there are people who will never want to get into Bitcoin no matter what it offers. Also, it seems you pitched it to your friend as an investment? If so, how about you discourse with him on how Bitcoin is more than an investment; how you can actually use it to make payment, send money, etc.
