Money that can be used as capital for business or investment would certainly be better not to be saved in any bank, because in seeking profits that can increase the amount of money to be even more is by turning the money into things that can bring in more than just saving it in the bank. I also agree with the opinion you said because at this time not many people have capital for business and investment matters so for those who have capital it would certainly be better to use it for those things.
There are different ways to invest money that is in your hand like your can invest in real estate, stock or any other business. One thing we have to keep in mind is that every business need prior knowledge for success. I won't get orofit if I invest money in real estate without proper knowledge and working rather I will end up losing money. While money sitting in banks depreciates in value, investing in business is also not risk free. I am not saying that not to invest in business but do proper working before going for any business.
