I think bitcoins grows more widely it has more advantages than banks or other sources. It is like a government facility and can enjoy in bitcoins.

That's why governments and big institutions will not allow bitcoins grow in wider range. They try their best to limit bitcoin growth.
Governments will either try to pass more and more licenses like BitLicense or will try to start their own cryptocurrency.
if government start their own Cryptocurrency then it will give Bitcoin more promotion and which the government doesn't want to happen.
With 2 halvings in near future Bitcoin prices will definitely increase, but it's too early to predict the prices.
Two halvings in near future? You are calling 5 years down the line as "near future"?
