Most alt are struggling to cross new ATH cause of the team the positive movement of those coin depends on the team and the demand of it. Bitcoin is absolutely different from any other coin though there are small small risk attached but it still remain one of the best, since alt investment is not certain I will rather invest in Bitcoin cause I believe no matter the behavior it will still appreciate cause they have a strong team and I believe they also have a great target.
As long as there is this coin, I really like it because it gives a lot of hope and the results are quite helpful and I made a good choice by adding Bitcoin and Ethereum because the opportunity to earn income is very good for the future so as therefore
altcoins which are considered to have very good performance for this year, which with buying altcoins is a promising opportunity with the current altcoin bullish market movement improving and hoping that way so on.
I have not seen any altcoin have been existing since or from last year to do well in this year and if you know anyone then you should name them. In the month of February this year, Ethereum was doing well and it was $4k and it lasted for about one week or there about and it started to decline again and since then it have not reach that price again.
And the second coin I can remember is Notcoin which was launched to the ecosystem recently and it is doing well. Those are the altcoins I know that have done well in this year. BNB is stagnant as it was. Solana is the worst and Pepe coin, dogecoin are not doing well and waiting the altcoins All Time High season to come.
