My younger sister told me that how you bear your pocket money because dad doesn't give you much money without education fees. I told my sister that I have a little investment in Bitcoin and I am a short term trader (though the fund is little). She told that she learned about Bitcoin at her ICT related books. But she has not much knowledge about it. Then I tried to teach him the basics of Bitcoin. At last I succeed though there are enough information to learn by my sister. She told me that she is interested to be a Bitcoin user. And already she started to keep some money from daily pocket money and after that she will invest in Bitcoin. I told that not only you but also other girls should learn about Bitcoin and Blockchain technology. She told me that she will share her experience about Bitcoin with her college friends. I am now much happy by sharing with my younger sister about Bitcoin and will be more happy if she share information and teach other friends.
Glad to hear you teach your sister about bitcoin kindly and patiently, i also have a younger sister, she lives in another city but we communicate quite often and i always remind her to invest in bitcoin because indeed bitcoin is the best investment at the moment besides gold
(previously my young sister liked to collect gold)currently, there are still very few people who know about Bitcoin and use it, when large adoption occurs, the price will increase drastically and only early investors will make big profits.
People who invest in gold are people who love to invest but love safety. Your advice to your sister to invest in bitcoin is absolutely right, but I think besides just focusing on the big profits that bitcoin brings, you should repeat over and over the risks your sister will face when investing in bitcoin. Both are investment assets, but in terms of risk, bitcoin is much riskier than gold, you need to tell her all the risks of bitcoin. I don't usually give investment advice to anyone, but if I do, I'm always talking about risk rather than return.
