Bitcoin has been proven and can be divided into tiny fractions, given the fact it is working it seems a safe bet for the future. It has failures, though. From an economic standpoint, if zcash replaces it in underground markets, will bitcoins legal uses keep its demand high? Will it continue to grow from speculation?
Bitcoin isn't private, tumbling it has huge risks and the end user has lots of security demands to remain anonymous. It may not be the best for underground uses whcih may have an economic impact. zcash is bitcoin but with its flaws ironed out.I do suspect it will grow like bitcoin but I'm interested in the dynamics.
Thoughts?
Just think that you are right but what will happen when all the bitcoiners will enter in the zcash then a big cloud will force the network of zcash , I mean the capacity of the other coins to handle the traffic of users is not comparable to the Bitcoin .
Here you can see that with the increase in the users the fee and confirmation time also increases.
So we can't remain with the economical growth of the coin , here for all the long term investment is only Bitcoin because Bitcoin has legality in many countries but not any altcoins ( except banking sector coins like ripple ) .
