I want to invest in all of the coins.
This is going to be the biggest mistake of your life. I'm serious.
but only a little capital owned.
This is the biggest problem of literally every single person in the world.
"I want to buy something but I don't have enough money or I want to do something but I don't know how"
Sorry, but you're talking like a little child.
If you have no money, get money by working for it or take a loan.
If you don't know what to invest in, buy bitcoin
