Hi Skot,
  The ViaBTC's minumum withdrawal of BTC is 0.0001 BTC. But I won't suggest to join the BTC sharing pool at ViaBTC pool. It's better to join BCH/XEC sharing pool.

  BTW, Beagle will give you more fun than only mining. Ex: host a BD (best difficulty) competition among friends, depending on weather situation to buy BTC (suppose you plan to do DCA for buying BTC)....
