ppcoin's inflation model is designed to be similar to bitcoin's even though without it's upper bound. You should look into details before assuming the worst.

Sure innovation has it's cost. When I decided to eliminate the upperbound and let Moore's Law and market force to determine money supply I expected some users would mistakenly reject it as a high inflation design. Yeah it's not as easy to understand as the 21M upperbound of bitcoin. But again, I was not there to boringly copy what bitcoin has to offer, but to make some unique contributions with the ppcoin project.
