So lets say we create a decentralized dropbox.
4 people are apart of this network.
1 person pays 10 ether to upload an mp3 file to the network.
The other 3 people are paid 1 ether a day to host encrypted pieces of the file.
What happens after 4 days? Does the file stop getting hosted since there is no ether left to incentive people to help store the file?
