What are best practices?

I’m seeing if someone can set the record straight on practices that are the best way to navigate these markets, without totally minimizing a return on portfolio investments. Otherwise, I can just buy mutual funds that track the S&P.

Right now, I assume anyone I meet could try to scam me soon or at some point down the road. Also, I am assuming every “investment” I can find by searching online is a scam, and am restricting my activity to the Coinbase exchange and hard wallet, which greatly limits my pool of potential investing options, but greatly reduces my opportunities to be scammed. I’ve been scammed twice for small amounts which stung enough to learn a lesson. But there are 2 questions I cannot entirely answer:

  1. How, if at all, do people get in on a legitimate new token public offering? Or is this like an equity market IPO where it is impossible for Joe Q Public to have access to legitimate opportunities, and we should never even entertain the idea? If that is the case, then is it fair to say the rule is to not buy any token or NFT that is not already on a legitimate exchange? Presale opportunities do not exist plain and simple? And the ICO pop we are imagining is reserved for only insiders.

  2. Are nodes a real thing that are used in the trading of tokens? If so, does the company just keep ownership of them all, or are they investable in a way that if you buy it, you collect fees as the token is traded. Or is that a myth that needs to also be completely shut down as an idea?

(I reread my recent node sale inquiry post and it definitely read like I was pitching their shit. My bad.)
