simple statement but its its true, NFT so far hasn't really been a good investment most of it are just getting driven by current hypes and thats it, once it losing its popularity so does the value also lost.
i've seen so many NFT that was valued so high, even millions, now doesn't even have any value, no one is trying to bid for it, so basically its valueless since there is no liquidity despite the fact that the owner giving it high value, if there's no liquidity whats the use then, basically it has lost all of its value now turning into worthless NFT.
the NFT that could hold on for long I assume is those utilised heavily in gaming platform, but even then, the gaming platform itself hardly retaining any community left, let alone their NFT. its overall just really bad investment.
The tech is promising. But without real use cases, why would you want to invest into an NFT in the first place? For what I know, NFTs are nothing more than purely-speculative investments. They're only driven by hype. If developers started thinking "outside of the box", things would've been different by now. All they care about is making money in the least time possible.
At least, not all hope is lost. With big companies joining the game (eg: Coca Cola, Pringles, etc), it should only be a matter of time before NFTs become useful. Who knows if the trend will survive alongside RWAs (Real World Assets) for the forseeable future? Just my opinion

There are NFTs that are profitable and worth buying these says especially those who are getting huge support from huge companies but there are also lots of scam NFTs nowadays. Scammers are now using NFTs to fool investors and they usually make it attractive and look profitable to gain their trust which I think is getting really common nowadays.
That's why skepticism is really necessary so we won't fall for scammers' trap. There are really potential NFTs these days but we can't say that they could last forever. Maybe they are reliable investment yet there's still no assurance about the duration that they could last.
