Permit me to give this that no future for altcoins where bitcoin is not sure to remain, which means they all depends on bitcoin to survive,they rely on bitcoin for their own determination of values, when bitcoin rises, to they also move along while few don't and remain on the same spot, same also is applicable when the bitcoin price goes dip, and hey also massively fall and some don't recover from such experience,so bitcoin should be your number one lead in cryptocurrency before I thinking about any alternative to it, know this that bitcoin cannot fail, it has come to stay.
