1. I do that but the same problem happens again that scamers have all kinds of ways to fool victims.
2. I take the example of privacy coins like (XRP) and decentralized coins like (ETH), you can redefine.
3. The value of coins depends on market demand, and good coins are of course widely used by its users, including coins that have high trading volumes.
4. Not a bad idea, I also like a few coins on that list.
5. Investment is always risky, there is no safe guarantee in the investment aspect, you yourself must determine your luck in the crypto industry.
Ok, that was very sad that you didn't find good one. Market has huge demand like Ethereum but maximum supply is unlimited. Although all coin has total supply limit but maximum isn't limit. Value only depends on supply. Still only top some coin has maximum supply like BTC 21 billions and frm has 331 billions.
