1. Not sure what your question with. I'm assuming you're thinking the blockchain length could get long enough that it's hard to store or verify completely? The size of Bitcoin's blockchain is currently around 115 GBs. Unless you're a miner or working with a sensitive transaction, you don't need the whole blockchain to operate. If I remember correctly, you could just 'ask' several reliable parties of whether or not your partial copy of the ledger is legitimate [1].

2. No, as the cost of the token or cryptocurrency goes up, the nominal price of service goes down. For example, Siacoin is currently around $0.015; let's assume it costs a dollar a month to store 1 TB. You would pay around 67 siacoin. However, as the value of siacoin goes up to $.02, you would only need to pay 50 siacoins instead (assuming the cost of storage is constant).
