No, Coinwarz is in fact HIGHLY INACCURATE & should not be trusted. A better site is whatmine.com
For example:
On Coinwarz the Einsteinium coin (EMC2) block reward is wrong. As per
https://bitcointalk.org/index.php?topic=494708.0 we are currently in Epoch 9-12 with 316678 blocks mined. The CURRENT block reward is 128 NOT 256 as stated on their site:
17:13:41

EDIT: Coinwarz responded & finally updated the block reward for EMC2 (though it did take several emails to get this fixed).
