Another way is to simply add a higher fee to your tx
This is from bitcoin wiki and is really useful if you want to be an autodidact usually the antpool method works fine with no extra fee needed.
Find the transaction ID (aka txid) of the stuck transaction. Almost all wallets have some way of doing this.
Search for the txid on
https://blockchain.info/On blockchain.info, in the footer, click Enable in "Advanced: Enable". If advanced mode is already enabled so that it instead says "Advanced: Disable", then don't disable it.
Write down the "size" number listed under "Summary". Call this value STUCK_SIZE. Also call the same value TOTAL_SIZE. The reason for having two names for the same thing is that you might later have to add to TOTAL_SIZE, but not to STUCK_SIZE. Separately, write down the "fees" number listed under "Inputs and outputs", and call this TOTAL_FEES.
On the left side of the green arrow near the top of the page will be one or more addresses. If any of them have a red U next to it, for each such address, click "Output".
For the transactions that it brings you to, add the size to TOTAL_SIZE, and the fees to TOTAL_FEES. Do this for all of the outputs listed with a red U.
If any of those transactions also have red 'U's, you have to follow those as well and add their sizes and fees to the running totals. And so on. You might have to go down several layers.
Now TOTAL_SIZE is the the total size (in bytes) of all unconfirmed ancestors of your stuck transaction, and TOTAL_FEES is the total fees (in BTC) for all unconfirmed ancestors of your stuck transaction.
Go to
https://estimatefee.com/. Around the middle-right of the page it'll say "nnn satoshis/byte", where nnn is some number. Remember this number as TARGET_FEERATE.
We need to estimate the additional size of your replacement or CPFP transaction. We'll call this value NEWTX_SIZE. If the transaction you're trying to unstick is one that you sent, estimate NEWTX_SIZE as 100. If the transaction you're trying to unstick is one that you received, estimate NEWTX_SIZE as 500. Later on this page, the section for your specific wallet might give you a different value for NEWTX_SIZE, in which case you should use that value instead.
Compute the following: [(TARGET_FEERATE / 100000000) * (TOTAL_SIZE + NEWTX_SIZE)] - TOTAL_FEES. The result is an estimate of the total fee that your new transaction will need to pay in BTC. For mBTC, multiply by 10-3; for bits/uBTC, 10-6; for satoshi, 10-8. This number is not per kB. If your wallet only allows you to specify fees in BTC/bits/satoshi per kB/byte, multiply the result by one of the following estimated conversion factors (we conservatively assume the worst-case 192-byte transaction for this estimation):
BTC/kB: 5.20833333333
bits/kB: 5208333.33333
satoshi/kB: 520833333.333
BTC/byte: 0.00520833333
bits/byte: 5208.33333333
satoshi/byte: 520833.333333
If blockchain.info doesn't have your transaction, you can use a different block explorer. blockchain.info is actually notoriously unreliable, but it has the best interface for this particular task.
Almost certainly, fine-tuning would result in a better fee rate, but the above instructions try to be very general and conservative (in the sense of having the highest chance of unsticking your transaction).
