There's only three ways the market can go: Up, down or sideways. If it goes up, hodlers are happy. If it goes down, new investors will be happy and people who still believe strongly in crypto will be happy because they get to add to their stacks. If it goes sideways, we'll probably see more cryptocurrencies being accepted as payment because volatility is the main reason that isn't happening.

See how basically every scenario is a win? That's why I'm optimistic for 2019. If you don't believe in crypto anymore then just sell. You'll probably be kicking yourself in future, though.
