I do have a question about the "Claiming" process, what is the ratio for bitcoin to CRE? Like one of my wallets has about 300 transactions and a "total received" of 4.4697 BTC ... would I only get 4.4697 CRE, or what is the deal there?
Yes, that is correct. The ratio between the coins are 1:1. There will be a maximum of 30 million bitcredits at the most. 15 million of those are claimable from Bitcoin. Considering that the block creation process is driven by a combined proof-of-work/proof-of-deposit algorithm, you will increase your chances of getting block creation rewards with help from your claimed coins.
Due to that the mining difficulty at the moment is at it's lowest, and will adjust upwards in a few days, you should probably try out mining if you want to gain some more bitcredits.
