When EU members Greenland and Denmark split in 1979 with home rule for each, neither had to adopt the euro and haven't to this day.
Scotland splitting from the UK is the same circumstance, either remaining in the EU would not be threatened with compulsory adoption of the euro.
Splitting away from an inclusive EU membership union doesn't constitute becoming a new member.

There is little doubt Flecc that the EU would almost certainly give credence to precedent should the UK be divided by Scotland's secession. Whether or not the Scots were to adopt the Euro or retain Sterling would probably depend on the demeanour of the Westminster elite and/or the Bank of England. Comparisons with smaller nations such as Ireland and Malta might be drawn which might suggest Euro rather than Sterling.
It is sometimes very difficult for me to respect opinions of people who simply regurgitate the headline stories from the tory media wing and seem incapable of interpreting what is really going on, both at home and abroad. How does one actually get through to someone so utterly brainwashed that they have lost the capacity for independent thought?
Adages and worthy quotations help my understanding and a couple spring to mind which fit appropriately with some of the blinkered stupidity I come across in the field of politics and world affairs:
'There's none so blind as those who will not see.' - This has its roots in the bible but has been used frequently in literature throughout the ages.
This is from one of Britain's greatest literary talents, Burns:
O, wad some Power the giftie gie us
To see oursels as others see us!
It wad frae monie a blunder free us,
An' foolish notion.”
