I know there are many doors to making money from crypto. but introduce them to the best.
The upside in altcoins is higher than that of bitcoin. So, asking people with $500 to invest in bitcoin will make them forever poor.
But of course, I respect your perspective way on investing in crypto.
IMO, higher potential returns in altcoins come with higher risk, and as we can see, how many altcoins have failed its value over time, whereas Bitcoin has established itself as a relatively more stable and widely accepted now. It seems like you're more into gambling in altcoin but if you can afford to lose that amount you invest and to deal with that high risk so, why not?
As a beginner, I wont recommend investing altcoins.
If you do, make sure you have the amount that you can afford to lose and don't expect too much ROI on it.
