Let's talk about the top 3 Major altcoins.
1- Ethereum
2 -XRP
3- DOT
Also, you can include your prediction on bitcoin's lowest amount this year if you think that altcoins movement are significantly related to bitcoin.
I don't think we will see a significant drop in cryptocurrencies this year, on the contrary, I believe that 2021 will be a year of growth. At the moment, we are already seeing how BTC and altcoins have shown new highs. ETH and DOT have already made their upward push and hit a high price. As for XRP, this is a dark horse at the moment, but I would not write off this coin at the moment, but the likelihood of its growth is slim. As for the price minimums, they probably will not be in this year 2021, in any case, this comes from the cyclical history of the development of the crypto market and 2021, the last year of the next cycle, and as history shows, every last year of the cycle, the cryptocurrency makes new maximums of its price.
