Yes, of course, we need altcoin, because it can make us have a good profit. And we can have some extra financial aside from our job. And this time altcoins are really in demand. As you can see it on news or internet.
Well yeah, altcoins are made so we can have back up that we can use when things messed up in bitcoin. Some altcoins started to be a shitcoin but eventually things favor with it and became a promising one and with this it can be a good source of income and eventually can give a good profit.
