LOL, just withdrew some BTC from an exchange, they are paying 0.00015936 XBT = $0.0924195 CAD per tx. just got 2 confirmations in like 2 minus.
Blocks are only full if your are not paying almost $0.10 per transaction.
We don't need to guesstimate:
From cointape.com, based on what is happening:
1-10 satoshi per byte = from 7 blocks to infinity.
11-20 satoshi per byte = from 2 blocks to 28
21-30 satoshi per byte = from 0 to 5 blocks
31-40 satoshi per byte = from 0 to 2 blocks
41-50 satoshi per byte = from 0 to 1 blocks
10 satoshi per byte = 0.011$ per 258byte tx
20 satoshi per byte = 0.022$ per 258byte tx
30 satoshi per byte = 0.033$ per 258byte tx
40 satoshi per byte = 0.044$ per 258byte tx
50 satoshi per byte = 0.055$ per 258byte tx
it's OK tho, when LN comes out fee will go right back to 1cent, because it will relieve a lot of pressure from the blockchain
