What altcoins you are holding?
I haven't invested in altcoins so far but I keep an eye on the altcoin market as it can provide good opportunities for trading and diversifying my portfolio. I also believe that some altcoins have the potential to grow and succeed in the long term, so I will continue to monitor the market and make decisions based on market trends and analysis. My first choice among alt coins is Ethereum. Also I am focusing on ADA, DOT, BNB, POL, SOL, MATIC from top alt coins. Until now I have hold Bitcoin. I am planning to invest and hold two more coins including Ethereum in the future.
You know all these and you still do not have any altcoin in your arsenal? That is not good enough.
There is no way altcoins will not outperform any assets you can think of in the financial market during the bull run, not even Bitcoin. Not having it is just a miss for you which I will never like repeating itself just like how I missed the opportunity to invest in Bitcoin during the early stage. And yes, you are so right, if we are investing in altcoins at all, the first considerations are the top ones, and I prefer the first 15 in market capitalization, unlike the higher number called out by the OP.
If I can select about 7-10 from them, then I can later go to the low in capitalization but with good projects. It is after then that I will end the selection with the new projects with good prospects. You better start making "hay when the sun shines," time is not waiting for anybody.
