I think 3 coins that have the best performance in 2021 are Doge, Shiba and Solana, and many analysts believe that the market that grew positively in 2021 because of the transaction volume of the 3 coins, unfortunately influencers like Elon Musk are now no longer active about crypto even when He bought Twitter does not seem to care about the market conditions that are still red today.
Doge, Shiba and Solana were able to improve in the last year is because Bitcoin didn't crash that much and market conditions looked stable and increased slowly which eventually became a lot. Now try to look at the market when Bitcoin experienced a very sharp decline in price, surely all meme coins and other coins also could not survive at a good or high price and this shows that the influence of Bitcoin in the market is still very large.
