GPU? dang your about 4 years too late, or found yourself in the wrong category.. maybe you're talking about altcoins
Yeah he's definitely talking about eth mining which really isn't ideal since that is mostly going asic now too, GPUs are nice for mining whatever is hot and selling it for Bitcoin, it's just a bit more working jumping on whats currently hot.
i do laugh at the ethereum crowd. worried about ASIC (strong hashpower) so want to go to a zero cost user-sign algo(ripe for a takeover). or go to GPU(weak hash) algo
thing about GPU vs ASIC is all the coins that go GPU and alter the algo to prevent asics, is that then AMD(ATi) rule the planet debate replaces ASIC manufacturers rul the planet.. sam argument just different company.
even with PoS people are already forming syndicates and combining coins to have more 'stake' to.. basically making stake pools to get more chances of winning rewards and then sharing out the proceeds. so even PoS has the same complaints as those saying PoW is bad..
the down side of PoS is that theres no cost to sign a block and so the zero cost does not form a baseline of support to help give a coin a good price support bottomline.which is why PoW coins fair better when they have good hashpower backing them
when it comes to altcoins they have always been focusing on how to play with people's emotions more so that they can create a bigger hype to pump their coin and make a bigger profit.
the thing about mining and ASICs have been a clear example.
there is a big drama going on with bitcoin that has been saying for years that bitcoin mining is centralized and they say it is so because of China and ASICs. so as a result when an altcoin wants to advertise they say they are "ASIC resistant" which is a big lie and is only said to pump the coin! it started from 2010 when LTC was created.
