Hello,
I've emptied my Electrum wallet to another cold wallet temporarily (currently a "zero" balance)... I have 3+ years of transactions in the ledger, and was wondering if there is a way to clear it out (more/less just to tidy up the look)... is it possible? Thanks!
And by ledger you mean the public Ledger (blockchain) ? If It's the case then no , It's impossible to do that as the whole purpose of it is to keep track of everything. If you sent everything to cold storage then It will be visible in the blockchain (only the addresses will be visible). If you want to hide your moves then It's better to use Bitmixer.io or just deposit your BTC into an exchange , wait sometime and withdraw them to your a new cold storage address.
