The original Bitcoin protocol is very innovative. However, there are several reasons for why today's cryptocurrencies will fail:
Nice where did you come from? anyhow we like some argument here:
lets go though your list, i intend to show you why innovation can matter and "Gen 2.0" crypto already exists.
1. Too slow transaction times for general use.
- Quark has an effective 30 second block time, and its in its "EQ period" (see down the list) - both of these things provide some robustness and security. ( also dynamic checkpoints which can be taken off any time)
--------------------------------------------------------
2. Too bloated block chain for mainstream adoption.
- certainly a potential problem but not a deal breaker when you see how Quark has solved the other "issues" Like many other decentralized system Cryptocurrency is similar to say for example "Torrents" - if users are running full nodes they are serving the network, should/could there be some incentive to do this in the future , sure why not. that's the "if we do nothing to the core" scenario, there are of course many other options.
--------------------------------------------------------
3. Having to store coins "under the mattress" is a step backwards.
i'm going to be honest i've not idea what you are talking about? but you could be referring to a theory I proposed which i've called the "use/collapse" paradox , where because mining monopoly in Bitcoin creates price manipulation if the manipulators "use" the entity (Bitcoin) this will cause the market to "price collapse" (Bitcoin) so this causes it to be in effect "kept under the mattress "
lets explain:
Quark is fully distributed except for the EQ reward, this gives benefits (many) and causes some perceived problems the benefits far outweigh the issues as Quark is priced by the market and moving forward will be used and utilized by the market.
--------------------------------------------------------
4. Proof of work will lead to too large transaction fees.
this ones my favorite but really i don't judge you for being ignorant of it - because when monopoly takes over any system, ignorance and humor grow usually.
The Quark EQ reward -
EQ)uilibrium R)eward is just a simple trickle amount of "inflation" 0.4% declining - that allows fees to be replaced, so its is the reward for mining not the generated fees.
To all intents and purposes Quark is fee free, (except for the protections on the "spam transactions"
It can be Fee free because of the this small amount of "inflation" ( which also effectively protects the network from monopoly)
Summary :
The EQ reward is a revolution in Crypto currency.
Quark is "fee free"
--------------------------------------------------------
5. Proof of stake leads to the rich getting richer.
True , generally, not sold on this one totally yet. it gets more complex.
(Quark is not PoS it has the EQ reward.)
--------------------------------------------------------
6. Lack of government support prevents mainstream use.
what's a "Government" oh you mean the guys that work directly for the people that issue the currency in to Debt?
the people that issue the currency into Debt are by default the leaders (in most cases) of the government.
next question:
Why would entities that issue debt money ever support ANY debt free system that means they lose all control over the "ongoing mechanics of debt issuance" ?
the answer is they won't and you are living in fantasy land if you think they will (just because.)
if they look like they are supporting it, its because they are either 1. actively destroying it. or 2. working towards that.
--------------------------------------------------------
7. Trading against ordinary fiat currencies causes volatility.
nope that's a Meme and a Myth as well - Quark solved it ( we believe )
have a look at the charts here:

volatility is caused because all (most) crypto are price manipulated - once Real economists (Shiller etc) understand "mining difficulty" they are going to 1. Slap themselves 2. laugh at you guys (just so you know)
