hello, i had 250 etc coins stored in my cew and 3 months ago i switched to emerald wallet. when i checked the wallet an hour ago, i saw my wallet was empty and i checked etc explorer, there was a transaction 1 week ago. did somebody hack and steal my coins?

i’m kinda noob, so any help would be appreciated.

If you did not moved the coins to 0xe693aED65257c1b9f6E0ceD129C136891Da9B77C by yourself then yes your coins are lost if i do not own the wallet with the private key.
