Sort of. With Awesome miner i used miningpoolhub.com and it kept all my coins in the wallet. I selected autotrade so that no matter what i mined it got traded for ETH.
It is worth switching when the price different is 20%! I set it up so that it could check every 10 min and if the price difference were greater than 10% it would switch.
Yea but you are paying miningpoolhub to do that for you so you are losing out on profits. I warn any miner away from any of these auto conversion sites. If you are auto converting to a single coin like ETH, you are leaving a crazy amount of future profit on the table.
