Very true, but then again, it also took nearly 2-3 years to actually gain value and traction. Wouldn't the counterargument be why build a position now when it will ultimately be eaten away by new coins on a daily basis? Why not re-evaluate in 2-3 years time when the majority of the coins have been mined?
Granted, numerous coins suffer from the effects of heavy inflation from daily coinage--take DOGE, LTC, VRT, etc. All have constant sell pressure from miners selling their stash. I realize not everyone sells, but there are plenty of examples showing how much value is loss from when these coins hit the exchanges.
I just offer you two new points of view:
1. Real world economics grows as e^t or t^n, where t being historical time. So it's derivative is roughly e^t or t^(n-1). Physical sense of this derivative is the supply per unit time. So real world economics supply per unit time is exponential or polynomial too.
Bitcoin & monero supply per unit time FADES DRAMMATICALLY as e^(-t) or t^(-n). Consider most 'dangerious' time intervals, dt << t, that exactly that intervals you are afraid of. One can see coin supply is roughly constant at such small time intervals. So overall coins volume is just t^1, t <-[t0, t0+dt].
What does all that mean? FORGET coin inflation completely, even on short-term future! It does not matter at all!
2. Instead of mining, consider how to introduce Monero to wider masses of people. Imagine, think about services around Monero, what can you deliver to people to be useful for them?
p.s.
Given that, you make Monero growing as e^t or t^n. It's much easier to achive, because Monero grows inside a population, no need for the whole polulation to grow! If you consider deeper, such a growing may actualy be explosive - that exactly what we observe with Bitcoin worth margin call exploded to 80000:1 since 2009 to 2014.
p.s.2. So I attract all the people to test rpcwallet, see welcome at Monero missive, Jul 6.
