Wanted: The Network incentivizing users to delete data off the network.
For example: User pays 10 Safecoin to put 1MB of data onto the network and user receives 1 Safecoin to delete 1MB of data.
Under the current design of PUT charges the incentive would be in “PUT” balance. So 100 puts for a file and get 10 puts added back to the balance.
Doing it in coins would see people treat the PUT cost algorithm as a “stock market”, or even be able to game it.
Say big player puts up terra bytes while PUT cost is extremely low, like one coin per 100 terra bytes (put cost can be lower can be lower @ 2^63 puts per coin). Then waits for network to be loaded and put cost is one coin per GB. So if you gave back 1/10 of the put cost in coins then they could get 10000x the coins (100TB/1GB=100000 & 1/10 = 10000 coins)
So for their one coin to upload they get 10 thousand coins.
So if a really big player got in early and offered 1000 TB in vaults and stored 100TB while the cost is 2^63 puts per coin, then later on when SAFE starts to fill up they remove their storage and the PUT cost rises a lot then delete their 100TB and winfall profit.
But if you only gave them put balance then all they get back is 1/10 of their PUTs done, so really 1/10 of what they had when they uploaded the 100TB, IE they lose if they tried that.
tl;dr
You cannot give coins in return for the delete incentive, the system cannot keep track of the coin cost to PUT data. The PUT balance can be bought at different times and at different costs. So best to just return a %age of deleted to their PUT balance

That was an incredible explanation.

Then I wish to change my wanted feature.

For example: User deletes 10 Puts of data from the network and receives credit for 1 Put of data.

I’d even go for 2. Maybe with an upper limit to remove any unconsidered gaming. The upper limit can change on SAFE update/upgrade if found too small a limit

This number could be flexible based on supply and demand.
Thats not a bad idea. If available space is low then 2.5 for every 10, and when space is plentiful 1 per 10. Might be too difficult for an upper limit since the network would only see individual chunks deleted at a time.
Wanted why? If the data is to be kept forever then what’s with deleting it at all? If any is to be deleted then how is a price to be decided that makes sense?
