Few questions

1: anyone know if there is a Linux version of multi pool miner or Mega Miner?

2: from what I have heard it sounds great. Auto switching to most profitable coin and keeping the coins you want and auto converting the ones you don’t back to the crypto currency of your choice. What am I missing? Sounds too good to be true. Do either of them mine ETH as well as claymore for example? Am I missing a ridiculously high mining fee? What’s the drawback other than lengthy configuration? Why isn’t everyone using one of them?

Keen to hear feedback

Thanks
