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.
Uh.... yea you have to have SC in your wallet in order to host files for others. The SC in your wallet becomes collateral so if you have a shit computer/connection and the files are never online then you lose your collateral. You dont just earn SC for nothing.
If you didnt have to provide collateral to host files then the whole network would be garbage and you wouldnt be able to access your files when you need to.
