Bitcoin has been the father of all crypto currencies and will be for 5 years or so. But with the rise of Altcoins in these few years we can speculate that bitcoin will get overtaken someday by some coin that can offer much more than bitcoin. I think there is already alot of these coins, but they lack media attention. It's the only reason bitcoin is not going to get into second place in near future. With this much progress in crypto, Altcoins may take cash place completely. You can already pay with them, but it's not that common. So overall, i think that Altcoins is the future and i would like to hear your opinions on this topic.
