Can clevermining use algo like Keccak and others and look at whatmine.com for the switch?
Heh. No. Definitively, obviously not.
Check yourself. Put 25ghs in the scrypt field, "25000000". Look at the volume (coin / day column) that would be mined if we slapped 25ghs on it and then look on the volume column. You'll see that if we mine it for even few minutes we'll destroy 99% of these coins.
