I thought about buying a used antminer online... but don't know how bad they get with reuse tbh, need to search BitcoinLE, first time hearing about it, but that whole metronome signal sounds really good and power saving! Doesn't it have security issues?
I might try to mine with my MSI GTX970 OC... need to get a script running on my other pc...
I am not sure I would purchase any SHA-256 specific hardware at this point unless you like playing around with stuff. There seems to be many better opportunities out there now for making coins.
Any low hash rate PoW coin has security issues. Usually the hash rate goes up as the coin gets more valuable though.
