i've said it once, i'll say it 1000 times. no coin will succeed long term if the coins don't have a purpose.
I thought that a lot last year with the alt craze in 1st quarter. However, all of them are still here; more or less successful. Even the less successful one's difficulty gets low enough and they are profitable; and get mined. Thus, they survive.
There are literally 100's of coins now, with no real purpose; save for one "cash money value". I'm not big on money / greedy, but I cannot deny this is the driving factor in the commodity that is "crypto".
If we were to reduce / hypothesize that only coins with purpose succeed, then we probably would only have 4 or 5 coins at most.
I do not intend, in any way, to dissuade from finding purpose and "marketing points" for UTC; however I cannot easily entertain, that it's what makes / breaks the coin. Not at all saying that purpose has no value, just that it's not the deciding factor.
Having said that, the "selling points' for UTC;
-Fast transactions
-Lower total coin numbers than many
-Highly resistant to coordinated attacks (51%)
-Community oriented
-Asic Resistant
-Long-term reward with stake / interest
-Semi-rapid block reward halving to increase rarity (10months appx)
-Less heat production from mining
-Energy conservation - less power running equipment
-Encourages larger smaller decentralized mining versus large centralized mining (i.e-BTC)
Many of those points are all "talking points" with most crypto's and are beneficial for UTC to have. Even the less obvious, Heat and energy savings. Power required to produce coins, was a point of issue with regulators in the recent Crypto meeting in NY. It is very possible that, as regulation rolls on; there will be more focus on the energy required. UTC stands in a good spot there versus; sha, scrypt and even nscrypt.
If we weren't able to get money for our crypto, crypto would be non-existant, unless there were a million times the merchants we have now accepting crypto (not just BTC, or a sextoy shop for all other coins, but hey, its a start?)
coins don't just vanish, they will always be around, just keep depreciating, but take CAGE for example, coin isn't even worth 1 satoshi anymore. CAGE process will continue down thru LTC, then DOGE. Treat coins as an ideal, they just don't die and disappear.
power/heat savings is card dependant, you can't say every gpu will save heat and power. u can say 'most' or 'some'. My cards still require 100% of the power they usedsince my day 1 of mining utc. if anything they would use more power since i had to increase my TC and -g 1 to -g 2. Killawatt proved i need 750 watts still. All other setting stayed the same. POS isn't worth leaving coins in wallet for a year when they could be making more money elsewhere.
While everything you listed is true, or half-true, it isn't enough to seperate UTC from the 275 other coins out there.
