Like BCH and BSV, they become exaggerated and not good for long-term holding. Yes, it may be profitable but for a short time. If you want to invest in cryptocurrencies, you should choose Bitcoin over BitcoinCash. Bitcoin is far more profitable in every way.
You said it properly.
Bitcoin is way to go and BCH and BSV are forks that always think of themselves as more superior than bitcoin.
Investing in those coins won't give you guarantee. They are centralized.
In bitcoin, you will get the risk as well but it's calculated and better than those coins because it's not centralized and manipulated.
