I listed 90 coins for trading but now I need to take a break from trading.
To avoid manually editing all 90 trade coins, I was thinking I could “export” my trade coins, use Excel to set “For Exchange” to FALSE, then re-import them.
However, I now notice that there is no way to import coins, and also that the exported list doesn't containing a unique ID that would let Numista know I am re-importing a coin I already have.
Is there a way to import coins from a spreadsheet or CSV?
