Ethereum will have adoption 3-5 years after bitcoin hits its full adoption. There is no utility to Ethereum now and we will all get plenty more opportunities to buy it even cheaper. Its great for 1000 people who code. Bitcoin needs adoption first. Bcash needs to be destroyed as a warning and punishment and than us pre-early adopters (not speculators) will repeat the benefits. Too much dumb money in the market like Nick Szabo said most of it in shit coins specifically Bcash.
Bitcoin market cap needs to approach 70-75% followed by Ethereum than litecoin which can act as a Lightning payment channel on ramp with atomic swaps. Thats all that is needed.
Let the dumb money be lost. Majority of it all flows up.
Please be careful with what you say. You dont want to give people false confidence. In reality cryptocurrency is a new area and it remains to be seen wether altcoins will be able to survive or bitcoin for that matter. But this is what makes them potentially good investments. High risk = High reward. But i think that the magic is disappearing and altcoins in particular will have a hard time because of this.
