As they say, it depends

In fact, it may be worth to move an insignificant part of your cryptoholdings to Ethereum (if you hadn't done so already) as we can expect some hype prior to Ethereum 2.0 release, which is scheduled to occur in January 2020. But then we shouldn't forget about the Bitcoin halving to come a few months later which should have an even more pronounced effect on Bitcoin's price (read, there should be more powerful price action). In other words, we will likely see a roller coaster in the coming months, and if you manage to time the market, it could pay back handsomely. Just my perspective, do your own due diligence at all times
