I guess the benefit of litecoin is that it is currently not possible to mine it with asics and fpgas.
ASICS are really what are making network decentralised by giving a lot of power to their respective owners.
I guess the reason it spiked, people moved mining litecoins. More ASICS = More gpus moved to other networks or sold.
What kind of benefit are you mentioning about? And who gets this benefit? ---> that benefit brings no value to LTC as a currency as well as merchant. It just protects some miners' investment in VGA only. It is totally personal issue, not BTC issue.
Eeverybody can buy ASIC rigs, right?
In real world, gold and silver are different natural substances. They co-exists by nature. However, BTC and LTC are artificially created. BTC does not need LTC as a silver counterpart. We have a single internet, we need a single internet currency only.
Eeverybody can buy ASIC rigs,
wrong. If I want to start mining I go and buy processors/videocards and compete against processors/videocards and even fpgas these things are readily avaliable. However i we look at asics:
Avalon = Limited quantity you cant sign up for any batch.
BFL = Started pre-orders poop-lot time ago never ever delivered.
So how can you buy ASIC readily? If we talk about decentralised system, then ASICS.
People with videocards moving with litecoins is market self-adjusting to unfair competition conditions.
BTW - if you have a small ASIC avaliable i'm buying it.
Also, as soon as GOX starts exchanging litecoins, the market avaliable for them will skyrocket drastically, since merchants would be payed in FIAT anyways.
