Now that scrypt/sha256 combo asic are jumping in the scene diff is rising again.
Alpha-t is shipping by the middle of July and I don't see reason why not to believe them.
What are the chances that another "BFL fail" will happen again.
With scrypt ASIC starting to come out, are we going to have a exponenitally increasing difficulty just as bitcoin?
maybe not rapid increasing as btc diff but it sure will send gpu mining out of the game much sooner than they last in btc mining. btc value was 4-5 times higher when asic-s arrived last year, even more later on. that's why gpu-s are lasted till summer in btc mining.
that will not be a case this time even if diff will not increase as fast as btc diff.
ltc value depends of btc value and it is always around 2.5.3% from btc value so for LTC to be worth $100, btc need's to be at least $3000-$3500 worth.
anyhow, even if we don't see exponentially increasing difficulty just as bitcoin gpu-s will soon be out of the game because value of ltc or other scrypt coins isn't going anywhere. at least not dramatically to save gpu-s.
