If Bitcoin should already hype, Alt's will benefit with a little delay, especially the Top ones. If you take a look at the Litecoin-Chart End of 2013 - it was an explosion. I expect the same for Lisk.
Litecoin exploded only cause it was like 99.99% the same as bitcoin. Lisk and ethereum is different from bitcoin, and their purpose differ from bitcoin.
The same happened with Peercoin and Dogecoin etc. The reason is not if something is similar or different to Bitcoin. If there is a pump there will be a dump, so people begin to sell. They could sell Bitcoin for fiat but a lot of Bitcoin go into Alts.
Plus: A Bitcoin-hype is the best marketing for Crypto in general, it attracts more people and more money. That's why it's good for the whole market.
And Lisk, as one of the serious projects with an innovative approach, will also benefit.
This year it was kinda opposite. When BTC went up, the alts went down. However, if enough money will pour into BTC, the alts may start rising too.
