For such high transaction you should pay at least 0.004btc for 1 btc and then you should get your transaction should get confirmed soon. and now a days sending small transaction is a headache for us.
0.004BTC is equal to more than $4!! I guess this is overkill...
A 100-200 bits transaction fee should do during normal days... Stress tests come once awhile but not often.I don't know if that's true, but I sent 0.005BTC to an exchange address five days ago and paid 0.001BTC fees to be confirmed quickly; yet it took two days to be confirmed. 20% paid as fees, and still delay for two days is simply absurd and very annoying.
