Unconfirmed transaction / double spend warning I transferred some coins from my Electrum Wallet to my Coinbase Wallet, however the transaction got stuck as unconfirmed (possibly because of low fees).  It has been already 19 days since the transaction, the coins are still showing as unconfirmed in Electrum wallet and I can not use them as well.

I am also getting a double-spend warning on BlockCypher.  How can I push this transaction through without losing my coins?
if the fee is not below 0.0001BTC/KB.    you can accelerate the transaction using viabtc accelerator.
