Altcoins are generally defined as all cryptocurrencies other than Bitcoin (BTC). And some people consider this altcoin very important or all. And in the future these Altcoins will move towards the goal. And innovations like privacy-enhancing technology will shape the future of altcoins
Not all altcoins are good for the market. More importantly, not all of them will deliver. A lot of projects are created out of nothing, so they disappear quickly. As far as privacy is concerned, it is good for us, but the regulator does not welcome such projects.
not all altcoins can be profitable, but it doesn't hurt to choose altcoins that have good potential, at least %10 of our assets should be altcoins, last year I invested in altcoins and saved it in just 1 year, from the beginning I bought $1k and was able to get a profit of almost $200k, from that profit I bought another altcoin this year and hope to get that kind of profit again.
