An S5 (or S1, S2, S3, S4, S4+, U2, U3) can be used to mine any coin that uses SHA256D. For example, BTC, NMC, HUC, MZC, CURE, TAK, PPC... all can be mined with that hardware.
Coins like LTC, DOGE, DASH, etc cannot be mined with that because they use different hashing algorithms (Scrypt, X11, etc).
Understood & thanks for taking time to answer me to all my newbie questions , I just didn't got into mining and was never interessted till now . even if I'am a Senior Member
