Due to high traffic on the Bitcoin blockchain, sending Bitcoin can be a pricy and slow process. Anyone who has been waiting in agony for their Bitcoin to arrive knows this. You don’t want to pay an arm and a leg in fees, and at the same time, you want to see you Bitcoin arrive safely in your wallet.
Stuck transactions are held in a pool called mempool where miners prioritise transaction depending the fees attached to them. If a transaction gets stuck for too long in the mempool, it will return to the original wallet. Paying a higher transaction fee increases your chances to be included in the next block. You can check out Bitcoin fees and estimated time here.
