it's not bad for nft coins, but it's still too risky if we have little funds because the possibility to increase still takes more time, indeed I agree it's better for coins like you said which are the best top 10 rankings in CMC / CoinGecko only or those that are not risky obviously bitcoin and etherum.
Choosing to invest in NFT coins is considered high risk because the price is unstable even in the bull market, NFT projects will be analyzed in terms of detailed project development and assessment of the NFT content offered in their projects. NFT may be more suitable for short term trading but for investment then the choice of top 10 coins is recommended because it is certainty oriented even though the upward movement is not significant.
