I propose to make investments exclusively in bitcoin as it is today the most dynamic and popular. Plus, he is the only one showing very strong growth. Which of the altcoins in the last 2 years was able to increase its price by 40% in 2 days. I don't think you'll find a coin like that. Investments in altcoins are unpromising. Don't think about it. For competent investments in altcoins, you need to wait for time and start investing in 2020. Then the situation will be more transparent and it will be possible to make the right choice.
