How can a newbie invest in good altcoins? I know about BTC and ETH but I think I can make more money from altcoins instead of BTC and ETH, I did my research and I have a few projects in mind but I don't know if they are worthy..
Avalanche, Mina protocol, Phala network and Aleph Zero to name a few
I think you better have some bitcoin in your portfolio, I agree with you that altcoins are more profitable than bitcoin but the higher the return, the higher the risk so you should not invest all your money in altcoins.
Smart investment is an investment that includes: a long-term portfolio and a short-term portfolio, reasonable capital allocation and always have contingency plans (long-term investment). Investing is always risky, so please research carefully and consider before investing.
