a. Learn what crypto coins are, primarily that Bitcoin is a specific coin with very specific hardware needs. The word 'Bitcoin' is not a general term for all crypto coins! BTC can only be mined with a miner made for processing the SHA256 algo and for several years now that means ASIC-based miners.

b. All the other coins fall under the general name of 'altcoins'. There are specific areas for alts here. Use them as altcoin queries are not welcome in Bitcoin areas. More to point of that is that the altcoin ares are where you find folks living/breathing alts so much better chance of answers there.

c. All ASIC-based miners such as the s9, A741, eBit9, and yes even the D3 can ONLY process the coin they were made for. The chips are hard-wired to do one thing and one thing only, that cannot be changed. Period.
