IMO solo mining is the way to go with a bitaxe.  

However it’s fun to mine on Ocean if only to experience the randomness and joy of sharing the small winnings of a block found.  I think that randomness is a great teaching moment for people new to bitcoin.  

As we move into this new area of increasing TH/s low cost micro miners things are going to get very interesting - both for solo mining and Ocean datum mining (where you build the block template).  

A bitaxe is gonna find a block and people will be stunned.
