Same problem as you electrum shows balance of 1.3 UBTC but can spend with same error
support@ub.com , I emailed support with address balances in question. I see zero UBTC on the block explorer, but before I imported keys to electrum there was a balance there, its all very odd. It looks like UB Electrum just steals your coins.
My electrum still shows coins though and green ticks
suggesting they are still there
?
Is there another way to collect the coins?
Or is this a scam coin to be avoided? I am guessing their support hasnt been in touch?
I really don't know support was in touch back and forth with screenshots and addresses. They said they forwarded it to dev team in ticket but nothing back since.
