I first gave information to a friend of mine who did not know what to invest in, about the areas he could invest in, and then asked him whether he was making the investment long-term or short-term. After getting the answers to these questions, I presented the options to my friend. The point I paid attention to is that I did not try to persuade or pressure my friend to invest, I just told him what I knew.
I said that Bitcoin always brings profit in the long run and reaches more people every day. Then I gave him a few ideas to learn about graphs and cycles. Finally, I warned my friend to remember that investing has risks.
