Yes well, inflation (actually: devaluation) isn't in the [immediate] interests of the currency holder. Terrible if you just want to speculate, which is 99% of the crypto market.
I'm no economist, but inflation should reflect an increse in growth and productivity. The fact that these coins don't tend to consistently devalue might say something about how useful they are for doing the job of a real currency.

An increase in growth and productivity should reflect deflation: more goods and services with the same amount of currency. Absent intervention, inflation simply does not happen as a long-term secular trend in a growing economy.
As mentioned in another thread, pre-modern US had growth rates higher than the modern US (~4%) with an immaterially changed CPI over a ~130 year period. This was with two punctuated sessions of central banks and wars which issued debt notes (currency).
In addition: it should be noted that Japan has had a deflationary currency for 30 years and is an economic dynamo. The only problematic aspect of that—which can be seen in the BOJ's recent ill-fated attempt to increase the interest rate—is it makes government debt (and all debt) harder to pay back. However the point remains: deflation has had an immaterial effect on standard of living.
