What is the point:
Never invest all your capital in one project.
I also support this point. We are not suppose to be selfish to the extent of putting all we have in one business. This is not the way to go, we need to invest in different coins.
If you want to succeed, then investing into different assets will gives you a great way to success. Investing in one coin is very risky especially if its just a Shitcoin. This is a golden rule on any investment form, better to grab more opportunities in the cryptomarket.
