For me I don't this think Altcoins are safe especially the Altcoins with low prices but just like before selecting an Altcoin you need to do your research it also applies to RWA tokens.
Did you mean altcoins with low marketcap? Because the price of a coin does not tell if it is worth going for or not, but some investors can use marketcap of a coin to know if they should invest in the coin or not.
Investing on RWA might be good but they are still altcoins although different from meme coins and some others yet this doesn’t ignore the fact that there are scam projects in this, I recall someone investing in something similar through Eth and now lost his funds, he came back here years later to find someone who could investigate it and find proof of scam but unfortunately this happened years ago no one couldn't, if I remember correctly.
It would be good if the project you sre referring to can be known? I prefer trusted ones like the token from ONDO and LINK. Why should someone go for unknown ones when there are better known ones from ONDO and LINK?
Also the PAXG, XAUT, XAG, SLVON and many other ones are real world assets. These assets are collateralized assets that have been existing on the traditional exchanges
