There are two coins out there now with the same technology, the same anonymity and the same features but it seems with two different directions for the future.
On the one hand there is SDC with a supply of 6,962,517 SDC and a current price of 0.0021 BTC
https://bitcointalk.org/index.php?topic=745352.0Then there is SPEC with a supply of 20,008,512 SPEC and a current price of 0.000030 BTC
https://bitcointalk.org/index.php?topic=1704473.0SDC appears to focus on the market function and SPEC seems to focus on greater anonymity.
SDC is 70 times more expensive than SPEC with the same tech. Are there any other SDC clones out there and what do you think will happen when SPEC hits Bittrex etc. and becomes more known?
