1. old chain, 10.3.2 and 10.2.1 will reject the transaction beyond 1 billion.
2. new chain, 10.3.3 will accept the transaction beyond 1 billion.
all people using 10.3.3 will be in the new chain
people will not lose their cents
need all people upgrade their client to 10.3.3
Rozu lets write to exchanges to add cent coins again ...
The best way to make update is put information about that in piggy wallet.
Make a bold note that : In 10-05-2014 wallet will change fork and you need to update it.
If everyone will see it in wallet they will make it.
What about exchanges ? did you talk about reopen market in cryptsy for example ?
