if we implement auxpow with btc we wouldn't have to sacrifice the 3-minute-blocks or would we?
This auxpow is does not exist (yet). I am not a fan of auxpow off the BTC network. Because that means we give up on the 'Fair' part of Uno. I suggest creating something that lets others tap into Aux Uno.
But I whisper this ... We invent auxpow sha256 ... test it on some other coins ... wait watch until uno makes 2 more halves ... and if it is all good then fine okay AuxPow into the Towers of Sauron. so you say: 'wait a little and do nothing' , right?
could turn out to be an option especially if we can raise the marketcap a decent bit in the meantime.
would love to hear the devs optionions on all this

option 3 would be: auxpow other coins with uno in which case uno remains unchanged. I think that's what you're suggesting, BN, correct?
Maybe that option 3 is a good way for now.
