This is no guarantee. If Vert, says, attain Litecoin #2 status and goes to, say, 100-200-500mn market cap, an ASIC manufacturer could create 100 VTC asics and never announce them as such but simply use them to gain an enormous share from the mining (that more than pays out his own development cost). He'd simply spread his hashpower around to various pools so that his hashpower doesn't seem very concentrated, and then rape the network while everyone is thinking that its just GPU-farms hashrate since "there are no ASICs".
What then? If there are no announced asics how can the devs take the initiative to proceed to a hardfork? Based on what? The mere suspicion that there are ASIC miners out there in the wild?
But in any case it is better than to sit and wait for the ASICs, the more that VTC could at any time change the POW function and ASICs remain out of work. In addition there are already services that allow to collect statistics on production of new blocks in the VTC network. And developers of VTC look on her.
You can't tell if an ASIC did it or a GPU farm found the block. You can see hashrates etc, but you cannot know the means involved.
P.S. What are you doing here? Bought ASIC for scrypt ?
Nope. Neither am I planning too.
Go to accelerate the difficult of scrypt forks :-). I made select - VTC is my favorite cryptocurrency. RIP LTC for me. Cryptocurrency must be improved against new threats. How to constantly improving methods security of banknote and banking systems. If this doesn't happen - cryptocurrency dies.
Everyone being on the same level (ie having access to ASICs) is an improvement against threats (leveling the playing field). But we've got some things backwards as GPU miners because we like to mine with GPU and not see our profits go down. A coin that pleases miners but isn't taking its network security seriously, is just deluding itself that it is better off with low-level mining equipment (when others could have developed orders of magnitude better mining equipment).
It's exactly the same with the collective delusion of cpu only coins that are at the same time mined by gpu clients that cpu miners are unaware. "It's a botnet", "it's a server farm" etc... yep, sure. That's the kind of delusion that awaits gpu miners when unannounced ASICs will take over. When you've played your own card by stating your intention that you'll shift PoW algorithm when ASICs get out, then it's simply logical that when ASICs are made, they will not be announced. They will simply mine on the network while everyone complains about how unprofitable the coins have become compared to the electricity that they are burning (because ASICs will be taking the bulk of the profit, masquarading as GPUs).
The cryptocurrency networks are more about securing the networks than benefiting a sub-optimal class of miners with excessive energy waste and low hashrates, like the GPU miners. And let's be honest here: Most GPU miners simply "love" certain coins because they can mine them and dump them. They don't care about centralization but rather maximum profit. That's why they end up in the largest pools, hurting the coins that they are mining.
