What do you mean how it is possible ?  It is simply possible to send BTC without including fees but the transaction will take long time to get confirmed or not get confirmed at all and will get back to the sender a few days .

That is not from BTC-e, amount transacted is 0.0001 which is below the minimum for BTC-e Bitcoin withdrawal (0.002). Sending a transaction with 0 fees is possible but it would take sometime unless your transaction priority is high enough, around 0.01-0.1BTC outputs, also a coin age of a few days.

This is BTC-e transfer from user deposit address to hot wallet.
BTC-e always sends such transactions without fees, because it does not need to confirm them fast.
It is just transferring funds form one pocket to another owned by same person.

Yes, it's a self swap from User's address to hot wallet. They usually do the same.

A lot of exchanges do that. If the tx is high priority, they'd just save that fee as a little profit while still charging client for that.

I think that $0.02 on wrong account is not a big problem for BTC-e  Grin

Matured coins generally do not require a fee, though I doubt whether all coins at BTC-e are matured.

More about transaction fee: https://en.bitcoin.it/wiki/Transaction_fees
That only apply to newly mined coins. Those coins are not newly generated so this doesn't apply. Any input that is not newly mined with 1 confirmation is considered to be matured. The main factor is the priority, it must be higher than 57,600,000 to have a high chance of confirmation. The formula for calculating priority is
Code:
priority = sum(input_value_in_base_units * input_age)/size_in_bytes

Where input age is coin age, 1BTC left untouched for one day has a coin age of 1 the amount of confirmation.

hum... this seems wrong!!!!
i read the link posted by FSB..

https://en.bitcoin.it/wiki/Transaction_fees

it seem who imput_age are the confirmation number..

and so,
if we have 1 btc coin with 144 confirm (144 is the expected number of blocks per day) the result is:

10000000 * 144  / 500(tx size in byte) = 2880000.
