why are the monero pools crashing now?

Hi,
I'm trying to transfer XMR from my wallet to an exchange. I try the command: transfer 0 {my-address} {amount} {id}
I get the error: transaction fee is not enough: 0.000001000000, minumim fee: 0.100000000000.
The amount I'm trying to transfer is 0.5 XMR. I'm using versin 0.8.8.3.

What should I do?

thanks
