I think just about any good altcoin is a better investment than bitcoin. When bitcoin reaches $3k it will most probably start growing faster. This in turn will lead to people wanting to look for something else and other altcoins will also start growing, and when both bitcoin and altcoins grow, altcoins make more value. And to top it all up, bitcoin is one of the worst cryptocurrencies technology-wise.

Anyway, always make your investment decisions based on long term prospects, not immediate prospects, because that way you most likely loose unless you know what you are doing by playing the market.
