Any top ten on coinmarketcap is a good altcoin wherein it has strong foundation already and many supporters and investors as well that alone is a good indications that that altcoin is a good to buy and hold that will do good in the next bull market. Take note, always invest what you can afford to lose hence in crypto is very volatile market which is very unpredictable.
I'm not agree with you, even any top 10 ranking coin will not be good investment, as like DOGE is included in top 10, you know it’s a pump & dump coin, it can't be safe investment for the future because of it’s a manipulated by someone (Elon Musk). And i think SOLANA also TRON seems not good in long term.
If you say Doge, TRX, SOL and all big cap coins are not good for investment then what should we choose?.
everything has the potential to be manipulated because all altcoins are still 50% centralized,
so it's only natural that the volatility of altcoins is large, but for technology, of course SOL and TRX are worth investing in.
the top ten on coinmarketcap indeed have the largest capitalization on cryptocurrencies. However, not all altcoins can be invested, because they include stable coins such as USDT. for sol and trx, this is an altcoin that has been around for a long time, if it survives, it's possible that it will get a pump too. but for meme coins I personally lack respect, because this is like a game that is driven by one person, if I want to buy it of course with wise funds
