That rate is long gone. Giga is going for about 0.00000045 BTC at the time of this reply. If you check https://masternodes.online/currencies/xg/, you'll see that the current Return On Investemnt (ROI) of a Giga masternode is 19 days. This means that if nothing changes, you'll get your masternode collateral back in about 19 days. However, as more masternodes come online, the time required to get back your collateral increases. So it means you have at least 19 days to get back your investment, and if the price of Giga doesnt fall, you can sell and make back your investment. Also the trajectory of Giga is pointing upwards meaning you may not have to wait that long to cash out.
