I generated BTC address through
https://wallet.aeternity.com/, i saved my seed, i sent BTC to this address and there is a problem.
I recovered seed in Electrum and this address is empty!
When i enter my seed here:
https://wallet.aeternity.com/ using laptop which i used to generate this seed i see different address (with my BTC) from this when i enter this seed using other machine! (without BTC).
What a scam site!
It worked for me, I'd recommend not generating the seed on site...
