Coins are still being mined, although the block reward keeps decreasing, miners also get transaction fees, so the more transactions with fees there are per block, the more bitcoins have mined/changed hands. At some point, the miners will only be mining for tx fess, however, by the time that comes, they could well be earning more mining tx fess than the block rewards today.
I'm still trying to understand this concept about "Blocks" and "Blockchains."
Are Blocks just digital records of transactions that need to be processed before they get approved and the Bitcoin changes hands? Is Mining lending your computer power to process these Blocks?
