In the aspect of choice of investment, You're right though cause their are some people who still believe in physical investment than digital ones, but one thing I believe is that the world is evolving very fast and it's gone digital and as the latest trend everything including investment is now switching to that dimension, that's why Cryptocurrency (especialy Bitcoin) is currently the latest trend for investors.
In my village, most people still prefer physical investment. Only some people who wants to join digital investment. I think the main problem is about lack of knowledge about digital investment. Also, people choose physical investment because it is a popular choice here. As time goes by, probably there will more people join digital investments including crypto.
It's not like other assets are not worth it or are useless but I think that as things are evolving, joining the latest trends is a very good option, moreover Bitcoin has proved over time to be a safer and one of the best assets for investment, all an investor just need is to take their time and study it, understand the trend before jumping into it then they'll be good to go.
Every investment must be worth it. It can't be called by investment if they are useless or not worth. But there are relatively safe investment, high-risk investment, and too risk investment. Bitcoin can be classified as a quite safe investment if we consider the growth of its price. People who assume it is high risk because they invest in lack of knowledge and don't understand how to deal with the volatility.
Surviving more than 10 years is enough prove for investors to see it's potential for the future
Exactly. Bitcoin has survived more than 10 years and its value keep raising. It actually proves perfectly the potential of Bitcoin for the future.
