We all know that lately there are more unconfirmed transactions. I am also waiting for confirmation by 5 days. Finally I found this link:
https://pool.viabtc.com/tools/txaccelerator/How does Transaction Accelerator work?With the Transaction Accelerator for delayed transactions, users can submit any TXID that includes a minimum 0.0001BTC/KB fee to ViaBTC. We will prioritize to include in the next block when possible at no extra charge. A maximum of 100 TXs submitted can be accelerated every hour.
Why does it take so long to confirm my transaction?When more people start to use Bitcoin, the Bitcoin block size grows to the 1MB limit. But Bitcoin Core developers keep refusing to increase block size for more people able to use Bitcoin.
I think this will help many people
