Some people only have one computer and that must suck. Fortunately I have multiple so I can use some of my alt-miners to do this safely.
So, for example, DASH master-holders bring their owners income (under the condition of maintaining the status "on-line") from coins mined by miners. If the formation of new altcoyin units takes place via POS-mining, then if the investor has funds in the local wallet and there are no operations with them in a certain period, the percentage "dribbles" on them.
