Why we should patronize investment over savings is that investmet provides more profit than savings. Let's take for example you save money in bank for 3 years, instead of making profit your money would be gradually deducted bit by bit for maintenance, transfer or SMS fee. But in investment like Bitcoin, volatility in Bitcoin will make it to increase, except the volatility is a negative volatile instead of positive volatility.
Investing means growing our money but some people prefer to save their money because they are uncertain about what kind of investment they will choose. Lack of investment knowledge would somehow affect their mindset and fuel their fear which I think was a good decision rather than losing our money. Investing should not be taken too easily as it gives a huge responsibility to the investor. Let us just do this if we think we can do it well but never try if doubts are in your mind.
