Actually, if difficulty goes up, the coin is more secure. That's debatable though because instead of 100 CPU miners, you will have 1 GPU miner. Some people will put up maybe a couple or a few of these, so 1 person could actually be equivalent to 200 or 300 CPU miners.
When everyone who has a 5 or 6 GPU mining rig starts mining this, then difficulty will go up.
After that, the exchanges will determine the price based on equivalent electricity expenditures of the miners because some or most miners will exchange their mined ESPERS to pay for their electricity and other expenses.
Like I mentioned earlier, I will keep solo CPU mining this coin half a day every day as long as I still get a block or two. Then I might consider joining one of the pools.
When there are too many GPU miners or difficulty is too high, ... maybe I'll turn off my CPU miner, as it won't be needed for the security of the blockchain anymore, and I'll be paying too much electricity.
Unless the price of the coin goes up. Yanno, something like more than 1 satoshi.
Here is the question we pose to everyone:
We've been working on a completely different algorithm to graft into HMQ.
If the community would like we can make this our top priority and fork the chain to resist GPU mining one more.
The new algorithm has never been used in any crypto chain unlike the ones that were used in hmq which were all pre existing.
Please make your voice heard. reduce the total coin supply , and make GPU mining a waste of time ... this will be better for the coin i think
there is alot fo people with strong rigs , when i saw gpu mining i was thinking in put my own rig to mine with 7 r9 280x(Gigabyte Windforce)
but my rig is in the other side of the city
but anyway maybe we should avoid gpu mining for now...
EDITED i am totally against to change the algo
