I never invested in gaming or RWA, and I invested a small amount in SHIB, hoping that it would be an alternative to dogecoin and some DeFi currencies like AVAX inj, as 2020 to 2023 were years where the price moved strongly towards DeFi tokens, but they were no longer as profitable as they were in the past.
Diversification of your portfolio is definitely recommended as it minimizes risks by a significant amount.
Investing in tokens is not considered diversification.
