I always say that cryptocurrency is unpredictable and that anything can happen. Things can work for good or may turn the other way round. Nevertheless, there are still great coins out there that are worthy to invest in especially in 2020 which is just two to three months away. I believe BTC, ETH,XRP and ripple will dominate the market next year.
I believe you made a mistake. Ripple and XRP are one and the same. The only Cryptocurrencies that have stood the test of time are those big cap ones and those with sustainable business models and plans. Like you, I wouldn't place big bets on smaller cap coins especially those bringing very little value on the table. My list includes everything in yours plus BNB and XLM (stellar Lumens). 2019 didn't play out as most of us hoped. Nevertheless, 2020 promises to be even better. Let's be on the watch out. More solid projects/startups will span out soon.
One solid cryptocurrency project that seems underrated is the Stellar lumens. The foundation has done alot of developmental work to improve this space as well as on board new cryptocurrency users through its adoption drive. BNB is also a worthy contender for the best projects in 2020. Its contemporary utilities makes it very indispensable and a strong competitor
