I consider altcoins a scaling solution. Profoundly censorship-resistant transfers of value are a serious business; there will always be plenty of new tokens out there for micro-transactions and shameless speculation. Every Doge will have its day.
I'd expect a sharp dot.com like wash out the next few months - (years).
There is not much room for 1k coins most like we have Amazon, Google, Ebay, Apple,Facebook. That's the market and off you go.
There will be washouts and more alts being born all the time. There is too much hot money washing around the globe to take any significant fraction of it onboard the tiny bitcoin boat, not to mention the pathetic tx limit.
