I tried to import almost 13000 private keys but Electrum is crashing each time... I've got them all in a single file, maybe I should try by spliting the file.
So let say I import private keys in a wallet_1, is it possible to add more adress later in the same wallet_1 ? Or do I need to create a new wallet ?
EDIT : Finally importing the 13000 private worked but took a while
