I can vault my own coins... thank you. I shake my head at this every time I see it.
"Here's an NFT for your 650k Cas 10." - HARD PASS
I wonder what a nightmare this would be for family members to reclaim what's theirs if the owner dies.
Everything about this is awful.
To each their own, I personally like that they have much better security than I could justify personally + can ship fully insured globally. I have sold a few larger denomination Cas coins before 4K and flying to meet up with someone to transfer them was always pretty stressful.
Totally willing to withdraw from the vault to a trusted forum escrow and accept payment in
BTC if preferred.
