1: I will never trust an exchange, most especially centralized exchanges e.g FTX Binance, etc.
Indeed, although we are using them, never trust them 100%. We have learned from some conditions so far, that although have high trust and reputation can also be crashed and then bankrupt. Moreover, centralized exchanges will also have certain interests something that will make one other competitor in whatever they want.
2: never n trust any other coin aside from Bitcoin for long-term goals, most especially the highly centralized altcoin as there are open to external influence just like centralized exchanges are also exposed to external influence.
This is the basis of investing in cryptocurrencies. So far, only Bitcoin is the most trusted for the long term. In fact, now I'm starting to have doubts and worries about some of the top altcoins. Because LUNA and FTX are tip projects and platforms that are very well known, but they can be destroyed very quickly. Hence, Bitcoin may be less risky compared to altcoins. But that doesn't mean zero risk
