It's my first message and I'm crying...
I had about 3.5 bitcoin, I tried to use some a short while ago and got a message that there is a compulsory upgrade.
I downloaded and installed the upgrade on my iMac, restarted Electrum, and then it happened...
It immediately said there was not enough funds to transfer the amount of ALL my coins but continued trying to process it until it eventually said there is a zero balance.
BOOM! EVERYTHING IS GONE!!
:-(
Sorry for your losses mate but this happens if you are lack of knowledge how Crypto wallets works.
You should have contacted the support please before doing this Hackers advice of upgrading.
Hope you will not lose interest in Crypto and will continue to invest in crypto,and use this as a learning experience mate.
