Block number and price should technically be an inverse relationship, all other things being equal. The higher the block number, the higher the supply of BTC, the lower the price point needed to match supply & demand.
Except the supply of USD increases too. Hell, I think they're about to print a few hundred billion more. :/
That's why I said "all other things being equal".
But since you brought it up...
Bitcoin currently has 6814250 coins in existance, and is inflating at a rate of roughly 8000 coins/day, or about 43% annually.
USD has historically inflated at a rate of about 3% annually.
