Use LTC ETH or even BCH for frequent withdraws .. then send to an exchange when you have saved up a bunch. BTC isn't worth it (even at .0005) unless you keep your coins on the site for a looooong time.
takes so long time and make double fees in the site exchange and the withdrawal fees
plus
all I have with BTC was 0.0025 and I want to move it to the blockcahin to have the fork's new coins
but I couldn't do that because they raised it to 0.0025 then when I got the 0.0025 They raised it to 0.0028 then the pool announced that it is reduced
I was very happy with that announcement
so I tried to make the withdrew but the system refused to do so
thanks
