Mine scrypt...
I highly doubt there will ever be an ASIC for scrypt, so GPUs are going to be the norm for scrypt mining.
Hard to tell. I think there are at least FPGA development efforts already underway. If LTC hangs around and becomes significantly more profitable than BTC due to hashrate not increasing as quickly as BTC, there might be incentive to do an ASIC run.
The main question is will ASIC mining of BTC kill all cryptocurrencies? It could because it will force people who are still using GPUs to mine SHA256(BTC) to switch to Scrypt(LTC) if they want to make any coin.
Yes, eventually all GPU miners will switch to scrypt as BTC hashrate rises and LTC and other scrypt coins become more profitable. That is, unless it doesn't become more profitable.
This will just make LTC/FTC/etc more difficult to come by.
Huh? All cryptos become
easier to come by as they get mined (there is more in circulation). Difficulty adjusts to keep production constant--I don't understand the logic here.
I just started mining last month, but overall I have only put in $140 to my "rig". I bought a 5850 for $80 and a 850W PSU for $60, and slapped them into my PC with a 6950 I already had. I get about 800MHash/s for BTC (800KHash/s for scrypt).
I've only made like $30 so far, and will likely piss that away with gambling, but I did it more for fun and experimentation.
My advice: Don't buy new hardware if you can avoid it. Spend $60-80 on a 5850 instead of $300 on a 7950 unless you just have a lot of extra income OR you want to upgrade your graphics card anyways.
I plan on getting a 7950 or 7970 next month but that will be going in another desktop that I will only mine with while I sleep/work.
I'm a n00b though, so I could be wrong, but I think there is still profit to make here. A lot of people pay some ridiculous amounts for electricity, too. I'm in Texas and pay $0.06/kwh... so it costs about $40 to leave my computer on all month. On average, I make ~$2-3/day right now, so I get a small profit, but it's not really about the money for me as much as it is the experience.
It's a way better hobby than smoking rock and playing dice.
Absolutely. Just as people gamble (and expect to lose), this can be a fun gamble as well. Personally, I'm trying to invest only in opportunities that appear to have a positive ROI. But everyone is different!
