Use these addresses found on the Internet:

https://www.blockchain.com/btc/address/18zuLTKQnLjp987LdxuYvjekYnNAvXif2b
https://www.blockchain.com/btc/address/1NT1jtYLNwFXLztD4U4B9sLizdYatirhWW
https://www.blockchain.com/btc/address/1f1miYFQWTzdLiCBxtHHnNiW7WAWPUccr

which contain transactions from every year, from 2009 to 2022. They sum up to:

8020.70182731 + 2500.00155992 + 10009.26282042 + 28151.05862779 + 10000.01672481 + 8000.00430382 = 66681.04586407 (btc)
(at time of testing)

Then move .electrum to another filename and start Electrum as:

run_electrum --oneserver --server electrum.bitcoinserver.nl:50514:s

and choose "Import Bitcoin addresses or private keys" and past the addresses:

18zuLTKQnLjp987LdxuYvjekYnNAvXif2b 1NT1jtYLNwFXLztD4U4B9sLizdYatirhWW 1f1miYFQWTzdLiCBxtHHnNiW7WAWPUccr 12tkqA9xSoowkzoERHMWNKsTey55YEBqkv 1KbrSKrT3GeEruTuuYYUSQ35JwKbrAWJYm 198aMn6ZYAczwrE5NvNTUMyJ5qkfy4g3Hi
