ETH will probably limp along for years like litecoin. It will be usurped for #2 by monero at some point though. Probably will hang out at #3 for a long time before someone brings a successful scalability focused crypto currency to market. At which time said project might surpass monero too.
Haha, can't tell if you are joking, Eth has the most active 3rd party developer group I've seen in crypto (along with plans to scale). Litecoin literally has zero developer activity. If Monero succeeds in becoming the defacto anonymous crypto (on dark markets), it will be targeted and banned across the world, taking heat off BTC. I would say Eth will pass BTC at some point or just be hacked into oblivion and be worth nothing, but stagnant is the last thing it will become.
Bitcoin will die in 2021 when Jinn Labs releases optical processor capable to calculate SHA256D at insane speed.
Unlikely. Sure all of the hashing will be concentrated with the people who get these first but that will be temporary and probably nothing bad will happen during that time. If you want to talk about what is going to kill bitcoin it starts with an m and ends with an onero.
Any thoughts on zerocash competing with monero?
