Transaction stuck because of low gas price

I've had a transaction with 12GWEI gas pending for almost 20hours now...during that time the LOW gas price was anywhere from 15-45 GWEI....what a joke. So is the damn thing going to go through or not?

I dont mean to hijack your thread but my question is very similar. Im sending SNX from Metamask, 29.59 Gwei (which it warned me was extremely low) but its been 3 days which im not sure is normal.

Hopefully somebody here can let me know if I should just wait longer?

Looking at your transaction, you have set a gas price of 4 gwei. Though not very high for current traffic, this should eventually get picked up. You can check gas prices and traffic on ETH Gas watch. That could help you decide if you want to pay a lower fee and wait longer for your transaction to be mined, or pay a higher fee to include it faster.

If it's not urgent and you don't mind, you can leave your transaction pending and wait for it to be mined. The estimated confirmation time according to Etherscan currently is +18 hrs. Although my experience is that it's usually quicker.

Keep in mind that future transactions, with a higher nonce, will remain pending too until the first one is approved. Transactions with a higher nonce can't be mined as you can't skip a nonce.

If you want to speed things up, you can either 'replace' or 'cancel' your original transaction by using the same nonce. Most wallets, such as Metamask, MyEtherWallet or MyCrypto support this.

Replace

Re-submit your original transaction with the same nonce (your current nonce is: 0) and a higher gas price. Check out a 'safe gas price' on ETH Gas watch. This will create a new transaction and will overwrite the first one, once it gets mined.

Cancel

Create a new transaction, to send 0 ETH to your own address, with the same nonce (your current nonce is: 0) and a higher gas price. Check out a 'safe gas price' on ETH Gas watch.

This creates a new transaction and prevents previous from being mined, basically canceling the transaction. This is recommended as it is not guaranteed that the second transaction will be mined first and invalidating your first. So you could end up with your original transaction being mined first.
