Now I tried and it and it appears in the top, so I went ahead again and try with my wallet details and loaded around 10k of addresses which I think is less but just to be sure, copied them and imported to Electrum and my balance remains 0.
any suggestions?
How did you copy around 10k of addresses into electrum so quickly?
The only thing you import is the list of private keys shown on that web page. This is an example list of private keys for the first five addresses that starts with 1EzCCawrCJf33TzwAhEY4ffUBABSACk5cz.

Was not quick but took around 15 minutes. Shall I try adding more and more BTC addresses until it appears in the electrum wallet? it will work?
Other question, if I keep putting new addresses and I check in the blockchain and there is no historial (no received no sent coins from that address) it means the address not exist in the wallet but if I create a new address that would be the next? because I just tried lots of addresses and none of them with balance.
