OLD ASIC MINER

[uinvestmoney]

I have old miner  htink might be 300GHZ are any coins still asic or they all script
if so would be worth rehooking up and mining

ASIC with hashing speeds of 300 GHz on SHA256 Algorithm will not even produce cents with the current difficulty.
With the release of newer generation ASIC, old ASIC tends to get obsolete very quickly.

That's a SHA256 miner, Scrypt ASIC in the CURRENT generation are still measured in MHash/sec not GHash/sec

 Unless you have free electric, or use it as a "cold days space heater", I'd not bother running the thing as it will LOSE money.
