You know it's a shame some of the bigger old coins are unprofitable to mine now. While they have a pretty healthy trade volume, their blockreward reached a point where it's not longer profitable to mine. Feathercoin for instance has healthy trade volume every day, but easily gets saturated by a handful of miners. Cryptonite is also in this boat.
But the rewards should not be too high. Look at LBRY for intance. The coin just crashed..But now the mining reward is decreasing slowly, and the price on the exchange will pickup.
I will launch a big coin soon. Make sure you mine with me in the early days.
Pure POW, No premine, Fair launch, fast optimized opensource GPU miners at start, No bullshit.
That was the whole reason I was talking about an adaptive emission model. If the coin is unhealthy, it will inevitably fold under the weight of mining, if it's healthy and can support miners it should also do that as mining generates interest, visibility, and productivity as well. There are some coins who solely exist because miners are perpetuating them.
Currently coin emission models follow a linear distribution that is often arbitrarily decided before the coin is ever launched (or it gets a lot of negativity if it's changed later on), but that never takes into account what happens to the coin later on. That's also why I've talked about a flat distribution model after an initial ramp up period (pretty much what Zcash is) as there is almost no way to decide how to distribute coins later on.
That's why you need an effective and dynamic system to take into account not only the health of the network (which we have already with difficulty retargeting), but also the health of the coin from a monetary standpoint (exchanges, volume is a generic indicator I'm using right now). No coin currently does this. Developers are often times keen on the technological aspect, but never on the economic aspect... Even the biggest current gen coins such as Ethereum and Zcash (Bitcoin and Litecoin are antiquated first gen coins) don't take this into account.
How much money a country mints every year is not set in stone and for good reason.
