I have been mining all from minerbest, so if I lost all the coins there, good bye Batman!
only until the fork, around block 3400,
plus maybe you should keep an eye on your pool more often when it comes to new cryptocurrencies, usually when the pool's hashrate is higher than the network's total hashrate for an extended period of time you can guess that there's a fork
its up to us miners to distribute the hashrate among a couple pools (more than two!!) since not a lot of people seem to be solo mining
Edit: plus compare your pools block with the blockexplorer every once in a while
