I have most of my investments in these two. But I think there's a lot of free space for other alt-coins to make some success
in the future, that will reflect on their price. Investing in alt-coins is risky, but it can be more profitable.
   Agree with both of you, Bitcoin and Ethereum will stay the best coins for 2020. Just few more months of this year, it will
be interesting to see statistic of this year, what coins made huge progress, who were the biggest failure in crypto-market.
