Thanks for the swap tip.  A great help. 

2 questions:  Is there a way to make a snapshot / back-up?  I moved halfway through the year and since the laws are different in both countries, my CPA's of each respective country might mess things up. 


Staking e.g. ECRV on curve (the actual "Staking" tx):
1. normal tx fee   √
2. Non-taxable income on newly acquired ECRV-GAU  √
3. Withdrawal ECRV
4. Deposit ECRV

3, 4-- Is this updating my cost-basis?  If I want to keep original cost basis, can I simply combine 3,4, and group them as a swap?
