Reason:
So, What is the reason? Why your transaction gets stuck?
The reason that you do not put enough fee to your transaction that is why it get stuck.
To know the perfect fee for the transaction I will refer you guys to this site https://bitcoinfees.21.co the current recommended fee is 420 satoshis/byte. However, I try to use 0.001 at least with my any transaction because we do not know the size of transactions before sending bitcoins. Users who are using blockchain.info blockchain automatically set fee, but it is somehow not correct it just predict the fee. Try to send the custom fee by going to advanced send option.
Perfect fee:
It is not possible to calculate the perfect fee of a transaction. The size of the transaction cannot be predicted, but keep in mind if you are sending transaction to multiple participants the size will be high so use double fee. As I mentioned above use this site to know the recommended fee https://bitcoinfees.21.co.
Transaction stuck?
No need to panic if have accidently sent your transaction with a low fee. There are some alternatives to confirm your transaction. Some sites provide this service free and some charges for it. They add your transaction in their own block when it is mined.
So, Here are some of them.
Free service:
ViaBtc is the free service to confirm transaction. https://www.viabtc.com/tools/txaccelerator/
This site has become so common that it is impossible to add your transaction. You will always get "submissions are beyond limit" error. So, I suggest you to add transaction when the hour starts ViaBtc uses UTC time. If you are in a real hurry and want to confirm your transaction they also provide paid service.
You can find that here https://www.viabtc.com/tools/txaccelerator/ on their site.
I am quoting it.
