The 1% thing used to be for all coins OTHER than BTC.
But now they added it for BTC, essentially 'stealing' 1% of the BTC of everyone who previously had BTC on there.
Usually exchanges do this kind of thing when they are short BTC, for example, Cryptsy recently had less BTC than it claimed to have in customer deposits, implemented a .5% fee to withdraw BTC, and accelerated their demise. After a stampede of withdrawals resulted in them running out of BTC, they ceased BTC withdrawals or slowed them to a halt as they could only send BTC out when some fool deposited some.
After this everyone started to spend all their BTC to buy alts, withdraw the alts, and sell them elsewhere to get their BTC back. The alts that could be withdrawn such as Doge and ETH were going for 30% premiums versus other exchanges. Eventually many of those shut down as they ran out of them as well.
It wont be the same at BTER because they have already been a zombie ever since the February 2015 'hack' (possibly insider job), stole over 7000 btc from them, or most of their user funds. But them implementing a 1% withdraw fee for bitcoin is an additional sign that they are in trouble and that they dont have enough BTC to cover what they owed, even after they gave their customers an 85% or whatever loss of their BTC.
