from last weeeeek, five transaction had been sent, but until now, they are unconfirmed.
is it associated with segwit, XT, classic? or block halves?
I am just a bitcoin user, and have no idea about this, please help..
thanks anyway.
It is likely not related to anything you listed.
What was the miner's fee for your transaction?
I always set 0.0001 BTC as the miner fee, it usually works
and even without the fee, the transactions can also be confirmed, but just late.
however, it has been take more than 7 days, and still 0 confirm. I think it's unusual
Yes usually it should work, but sometimes there are many other transactions waiting to get into
a block, and they may also be using 0.0001 or even a higher fee so they can get into the block first.
It is important, when setting your own custom miner fee, to check the status of the mempool and
estimated fee, so that you do not underpay, in those situations.
You can figure out the fee you should basically pay from these two links:
https://bitcoinfees.21.co/https://bitcoinfees.github.io/You can see the total number of txs in the mempool from these two links:
http://statoshi.info/dashboard/db/transactionshttps://tradeblock.com/bitcoin/In addition, if you pay 0.0001 in miner's fee, that amount is based on that your tx size is less than
1000 bytes. You should pay around 0.0001 btc per every 1000 bytes as a basic rule when using custom fees.
If you use specific wallets, like bitcoin core, they can estimate the fee for you and you will only pay what
the minimum amount needed, without overpaying.
Hopefully this isn't too confusing and will lead you toward a better understanding.
Edit: You can no longer set no fee. That has now been phased out.
That transaction will never be placed into a block and is better to pay something than nothing at all.
If it has really taken 7 days and still with no confirmation it is likely because you paid no fee.
Please wait for it to return to your wallet before doing anything with it.
If you have no problem with sharing your Transaction ID, I can take a look and see what the issue
may actually be. But either way, it is mostly likely related to fees.
