Nobody knows, it depends on how many people use the network, supply and demand etc. Remember that Safecoins are "burned’ when someone PUTs data to the network. So the more people store new data on the network, the more coin get out of circulation. Same for structured data which is way more expensive, if we have a lot of structured data on the network, a lot of coins are burned so to speak.
It also depends on the algo’s used for Farming. Are new coins created to easily?? Less people will Farm them as the money they make is to low. So now the Farming Reward goes up and people can make a bit more again.
So, nobody really knows. We’ll see with test_Safecoin.
Not yet but it will be possible. I think it’s a good thing:
