I will create a forked chain of bitcoin to accomdate for broad adaptation.
The only major change from the old chain is:
Reward of 200 BTC per block for each new block - (never changed)- The chain will produce 10.5 million coins/year (which is far from enough to cause inflation)
- The clients (incl source) running the new fork will be made available well ahead of the fork
- All bitcoins created before the fork will by nature be contained in the new chain
Bitcoin already accommodates broad adoption because they are divisible to 8 decimal places.
What you propose is something that has already been discussed. Your fork won't work because the forked coins won't ever have comparable value to bitcoins. The people that hold bitcoins and others interested in their value, like merchants/miners, won't support forked coins that look to disrupt bitcoin in economically messy ways. If they did then what's to stop other forks after your fork?
Bitcoins have value because people accept them. Your forked coins wouldn't be accepted on the orignial bitcoin chain, yet holders of original bitcoins could still spend their coins on your fork, so you haven't taken away wealth from people with many coins at all.
Also, all possible bitcoins are not already held by people, only about half of total bitcoins exist so far. Last, for your coins to even have a chance at comparable value to bitcoins there should be less of them not more.
