Np man. Thats why we, boobs (in BF4 i like to say boobs to noobs, to not offend the kids), must talk to eachother anything that comes in our mind to not loose.
That tiny things can save us money and learn well what to do.

Anyway, i still don't understand what time to take in consideration in a transfer and how we can quantify it when we want to transfer or deposit.
I found that here:

https://blockchain.info/unconfirmed-transactions

can see unconfirmed BTC transactions.
Few months ago, there were in number of over 30 - 40.000. So many in queue, where i believe, to have a quicker transaction you must give more money (fee) to the miners. That only if your exchange let you do that...
Now they are in small numbers. I see around 1500 transactions pending. But they are moving quick...

Can we do a math having in mind that figures and the time of confirmation for a transaction?
At my first BTC deposit (2 days ago) i saw there were needed 3 confirmations, not 7 as i heard it should.

Maybe will understand that in the near future.
