I've come into "some funds" that were once lost, I was contacted by someone from a bank in the UK to open an electrum account to see the funds and withdraw them too. In my default account it 1st showed me the lump sum I was told I would withdraw then Bitcoin went up and the money increased, once it increased it showed me a minus on my balance but was told the money is still there. So I opened another account as a "holding/personal account" to use between Electrum and Luno and practice moving the money. when it was time to withdraw I was told to put in a large amount of money to create a history between my accounts and once I move the money to Electrum "Holding/Personal wallet" the balance from the Default wallet would appear. Can someone assist on the legitimacy of this please.
Also in my personal research it shows Electrum doesn't have a support/email account but I recently received an email from
contact@supportelectrum.co about the funds. is this also a legitimate account from electrum?
your advice will be highly appreciated, thank you.
