Can someone clarify why voting on 1 is such a great idea (and so aggressively promoted here)?
Voting low will decrease the coin supply, and once you have a price set, lower supply gives more time for demand to build up. If you pair that with good development and promotion, demand raises, beats supply and that pushes price up.
Thanks for the clear explanation.
Do I need to keep the wallet app running for that, or enough just to change and save?
The effects of votes require for starters that you mine. If you are mining with the wallet, you have to leave it open (or the corresponding daemon running in Linux) but finding blocks solo is extremely difficult unless you have a hell of a machine cpu wise. So you better mine in a pool using their miner. Right now you have three options:
http://hvc.1gh.com/,
http://heavycoinpool.com and
http://hvc.nonce-pool.com/. People are reporting at the moment lower hashrates in heavycoinpool, so you may want to use one of the others. I'd recommend
http://hvc.nonce-pool.com/ to distribute the hashrate, so far 1gh hoarded too much.
And some thoughts... votes that count are the ones cast by block finders. And this is one of the cruxes of this coin... generally block finders will be people with a lot of overall hashing power. If they're in for a quick buck, they will want to increase block content and vote high so they can harvest more coins and sell them. One of the keys for this community to succeed is to avoid quick dumping so there's time to develop and grow sustainably. That requires to give reasons to powerful miners for 1) Holding, and/or 2) Voting Low.
Getting heavy miners to vote low seems difficult. If I could throw in a LOT of hashes, I'd like to have more coins even if I intended to hold - so once the coin hit my target price, I could get higher returns. So at least we suggest the average miner Joe (or anyone wanting to build things around HVC) to vote low in an attempt to counteract the expected, more frequent high votes of heavy miners, because a long, steady growth of HVC is more attractive for both small miners and community pushers.
So it seems that the best way to avoid quick dumping is to develop the coin and the community and to build expectation. That works for everyone even if blocks are voted to be big.
