"Another source of income"
If you invest at the wrong time, such as during the BTC crash, and then sell because of fomo, your money may be lost.
In this pandemic, eCash is already sufficient for purchases, as it uses fiat digitally rather than digital currency such as crypto, whose prices fluctuate daily. When it comes to payment, I still prefer eCash because the transaction fee on crypto is very high, and I can't afford to use it in transactions. However, I may use it for investing and hodling to make a profit.
If you do not know very well about bitcoin then you should not invest into bitcoin that is the end of it. If you are interested in making profit right away, buy some bitcoins and because it dropped in value and you sold because of FUD that means you should have not go into bitcoin from the start.
The point of bitcoin is that it is a powerful tool against inflation and devaluation of the fiat money and if you own bitcoin in the long run you are going to profit from it, doesn't matter when you buy it, if you wait long enough you will profit.
People who bought at the peak of 20k in 2017 could have made x3 of their profit if they waited for 4 years, there are not that many things that can give you x3 profit in 4 years, so even they profited more than anyone. People who buy from 60k will profit as well, maybe this year, maybe 5 years later but they will profit a lot. So anyone who panics and sells should not be involved at all.
