Well even if signature campaigns give us less earnings, it is still steady. And i agree that keeping a lot of bitcoins can't be considered as steady income because the price is fluctuating and we won't be getting enough here on a consistent basis.
Yeah holding back or investing in dibitcoin is not steady income because the fluctuations in bitcoin happen very often, you do not even know when you'll earn by selling bitcoin, because you do not know when the price will go up and you can sell it unless you invest in a mining site, May give you a steady income
