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.
it is totally his choice to make the decision to invest or not to invest in Bitcoin based on whatever reason that he choose to hold on to. And let me reiterate this here, Bitcoin isn't the only profitable thing one can invest his money into, there are lots of other ways one can make investment depending on what the person feels comfortable with. I know a relative that has a lot of money but wouldn't want to make any investment that is outside of business. He feels that since he can see the physical business and monitor it growth, he his satisfied with that. Others might not think in that direction but you just have to allow them be and stick with what works best for you.
