Why am I not surprised? in order to host files and earn money I'd need to have 2000 tokens in my wallet, this is like steemit, have some steem to have power when you up vote people and then earn money, no thanks.
Ofcrouse u would have to.
It's a kind of collateral, in order to be a part of the network you have to invest in the network, it is also helps to prevent attacks by nodes, which will keep out from attacking because they have a collateral to lose.
SC is pretty cheap now and 2000 tokens worth less then 2$, can't see a reason why someone who wants to earn from hosting files will give up on it just because he has to have a small collateral
