Altcoins is good for trading and people get profit easily. Altcoins pump and dump very fastly so some people choice it for trading. But all people not use altcoins for day trading. Some people hold it for long term. So i say It's totally depends on Project which you choice.
Many of the top altcoins are great for long-term investments, but not all are good because there is certainly a risk in choosing to invest. I will usually choose coins that are in the top 10 CMC because these coins do not fluctuate much and will often depend a lot on the price of Bitcoin.
Of course, choose to add new coins that have just launched in this market because if you are lucky you will make a profit from x5 to x10 compared to the original.
5-10 times profits can give you any top altcoins for a big announcement. You can check Binance coin, Litecoin, Vechain or Chainlink. If you lucky than 5000 percent profits could be possible.
