You need some stomach to hold cryptocurrencies for the long term. It doesn't matter how big whales trade in the interim, because a good coin will definitely appreciate in value in the long term.
The top tier altcoins will definitely keep gaining value steered forward by Bitcoin, but what is your definition of a 'good coin'? Is it a coin with an actual purpose behind it, which differentiates itself from the shitload of other coins in terms of engineering, or do you consider 'good coins' to be coins with large communities behind them? Or both? Dogecoin is the perfect example of a community based coin that doesn't have anything to add aside from that. It has been a decent performer throughout the years, but greatly outperformed by coins actually serving a purpose with strong technical engineering. Bitcoin itself is and remains the safest 'bet'. Safe means less extreme reward potential, but also less extreme downward potential.
