Slightly off topic but all the same about the mining pools:
could someone tell me a good article or a good explanation on how to handle txfee on all these pools.
How do you choose the right level of automatic payment so that it does not cost too much depending on its mining power?
What is the difference between TxFee in percentages and that in fixed rate? When do I have to transfer to minimize all these fees?
Many pools do a fixed fee if you withdraw below a certain threshold, but no fee if above. For example, right now, ethermine.org lets you set your auto payout threshold:
Payment threshold in Ether (Min: 0.05 Ether, Max: 10 Ether, if set to less than 1 Ether a fixed tx fee of 0.001 Ether will be deducted from the paid amount).
So, if you set it to pay out every time it reaches 1 Ether, you pay no fee. That's the way to save.
If that is too long for you, and you don't want to hold it as Ether that long, set a lower threshold, like .5 Ether... but you'll pay a .001 Ether fee each time.
You can go as small as you like, down to .05 Ether, but the fee stays .001, so the smaller your withdrawal the bigger the fee, as a percentage.
Withdraw .5 means .001/.5 = 0.2% fee.
Withdraw .1 means .001/.1 = 1% fee.
Withdraw .05 means .001/.05 = 2% fee.
But withdrawing at 1 (or more) means no fee. That's the way to avoid, in a fixed-fee pool. Set your withdrawal as high as you can, or go for the level that is "free."
Just interesting what is an ANN pages?
