can exchange my btc to ltc it is not available on my region
Where are you trying to exchange? I believe sites such as ShapeShift.io would allow you to make the exchange without a problem. Or FortuneJack has an on-site currency exchange platform? I'm pretty sure either one of those should do the trick and if not, I can set you up with a VPN and guide.
In regards to your original question, Coinbase is pretty smart. They'd probably detect any average VPN/proxy you use to bypass the filters and the fees; you're just gonna have to suck them up for now. Shame how high they've gotten recently.
coinbase transaction fee is just too high. for a 0.0002btc transaction I need to pay 0.0006. crap right?
thats just wayyyy too much I hope I can find a way to withdraw my btc without enduring this high fees
