I think you will only hoard storage promise of space, so that is OK. The safecoin will be consumed by the network and farmed out.
So putting more into storage means you just gave to farmers more who will hopefully distribute it (well it’s distributed to them). When you need to use that space you hoarded (expensively) the network will ensure you get it even if it has to increase famers rewards to do so.
Hope that makes sense I know I am very bad at explaining this. It will be much clearer when we implement it as my head won’t be in routing algorithms
