To my followers who keep asking me about what alt coins to invest in. I would like to remind you that I'm a hard BTC investor and not a crypto trader. Thus, my opinion would always be: if its not bitcoin, its a shitcoin.
But if i were to give an answer solely based on analytics and market trading volumes, i do have a couple suggestions. XRP is one of those coins that is not entirely reflected by the main coin market. It performs well in the early days of the main coin bull runs but then follows different trajectories as the bull run continues. However during bear markets it is a good coin to make profits on. DOGE despite being a meme coin also has one of the largest trading volumes in the alt coin market and is even projected to achieve a 1$ or even 2$ valuation by 2025. Its a gamble, but something to consider. SOL like ETH has a reputable blockchain network behind it and is also a very reliable coin. PEPE is much like DOGE in terms of a gamble but also a coin that could perform well in time.
There's definitely a lot more alt coins that are reliable, but i suggest you do an extensive research on anything else you're considering on buying. Also beware creators that try to sell you coins that are literal dogshit just so THEY turn a profit out of it while you end up losing money. Make sure you stick to 1 or 2 reliable and old-timer crypto professionals that know what they are doing and acquire the information you need from them and only them.
It is also useful to remember that most alt coins only start performing well during the main coin bear market in what crypto traders call "Alt season". However, during main coin bull runs people tend to pull out their money from alts to trade in the main coins. Thus, even though some alts could keep performing well, don't expect as much appreciation or profits as the ones you'd expect during peak alt season when people move their money from main coins to the alt market.
Again, I'm the worst person to ask for advice on this topic and i urge you to ask someone more knowledgeable than me. But, this is my 1 2.
