its a noob question but can i mine any altcoin with any miner for example lets say antminer s3 can i mine peercoin dogecoin or anyother coin with antminer s3 ? or it is only made for bitcoins ?
you need to know wich type o ALGO the coin use.
for example if you want to mine bitcoin, you need an SHA 256 asic miner.
if you want to mine doge or litecoin you need an scrypt asic miner...
and so on...
which mean i can mine any altcoin with any scrypt miner ?
It all depends of what coin you want to mine. Each coin uses it's own specific algorithm, some have the same algorithm. You have to, in order to get profit, purchase a miner capable of the coin you want to mine's algorithm.
Thank You Both
