My little thinking is
For bank investment:
Risk free
Low profit
Get profit for a certain period of time
Banks are risk free for investment, but in the country where I live, there is no effort to deposit money in the bank. But whenever I enter the bank to withdraw money, I have to face various kinds of harassment. And if I go in in the morning it takes almost noon for me to withdraw money, and I have to suffer all kinds of harassment.
For bitcoin investment:
Risky
More profit
Anytime you are rich
But if I invest in Bitcoin I can invest anytime, and withdraw anytime. Basically I own my assets and no one else can enjoy them if the keys are kept under control. Investing in Bitcoin is not risky, but the benefits are high. Short time and not having to be harassed by anyone so in any way I can see the advantages of Bitcoin.
I equated everything to keeping money in a bank with third party control, and investing in Bitcoins owning your own assets to withdraw at any time. So I will never let a third party control my money that's why I hold more bitcoins.
