yerr nahh, couldnt find the tool link without signing up.... found it today tho'

i've ended up re-sending it with a correct fee. This is my second use of a wallet and im surprised at the fee, 266.841 sat/B , i thought it would be lower. To tx usd $81 it's cost me $3. I realise it would be less if there wasn't two outputs, but still aroun $2... that is unless ive done something wrong but i don't think so.

It was a bit scary seeing it come up on blockchain as a double spend but im impressed with how quickly the system realised it was a resend and adjusted stuff accordingly.

thanks for all your help, my fee was for a couple of hours away so should be all good...

happy you got it solved

As for the high fee... Indeed, there are a lot of unconfirmed tx's being broadcasted lately. This causes some sort of fee-bidding war (since transactions with the highest fee per byte of tx data usually get picked by the miners). There are times when the fees are a lot lower than they are right now tough

.

Technically, you can estimate your fee this way:
tx size =~ nr of inputs*147 + nr of outputs*34 + 10 + number of inputs

In your case:
tx size =~ (2 x 147) + (1 x 34) + 10 + 2 = 340 bytes

https://bitcoinfees.21.co/ teaches us the optimal fee at this time is 450 satoshi's/byte

So:
340 * 450 = 153.000 satoshi's = 0.00153 BTC =~ $6.4 (at current preev rate).
However, this is like the optimal fee for which you have a 95% chance of your tx ending up in one of the next 3 blocks... The fee you added should be more than sufficient if you're willing to wait a couple of hours.
