I have mixed views on this because most currencies stay stable with some sort of inflation. Quite frankly you shouldn't be inflating by 2% per month as thst a huge market but I don't think anyone would be against an increase for this to be accepted as a currency.
The alternative view is that this is what altcoins are for and most of the people won't see the last block with the initial rewards being taken up but at a point where we're at a low number of bitcoins per block it may come in handy to increase inflation slightly although if it becomes unprofitable to mine it'll be the node owners doing the mining which wouldn't be a bad thing (each node miner with a few chips to mine with like the gekkos side hack makes - id be into that).
The 21 million total bitcoin cap isn't as important as most of the people think.Great mining difficulty reduces the mining of new bitcoins and keeps the supply low.The 21 million cap is just a psychological barrier that creates some trust amongst the newbies that the bitcoin price will keep going up,as long as there is increased demand for btc.Inflation would be bad for btc.
what are you talking about? the cap that bitcoin has is one of the most important features of it that has set it apart from all other currencies that for 100 years had no cap whatsoever! and the number that was chosen (21 million) is a pretty good one, although Satoshi never said anything about why it was chosen but now we know that it is appropriate as it is not too much to negate the cap (like most altcoins make the mistake of having such a huge one) and it is not too small to cause users feel there is scarcity.
