I did a few different BTC transactions today and they all went perfectly smoothly moving money from different wallets. However, now when I went to pay a seller, there have been zero confirmations going on one hour. The fee I paid was over 4 USD (0.000904 BTC) and the transaction itself was under $100. Is it normal for it to take this long? I know this is likely a noob question but the only threads I could find similar to this were months old when BTC was a much different price and before the fork, and I don't know if that changed this
Looks like you paid a sufficent fee according to http://bitcoinfees.21.co/
If your desperate you can always pay a fee to have your transaction accelerated through viabtc.
