Could you please elaborate on the steps required to successfully add Siacoin to my Trust Wallet? I'm familiar with managing other cryptocurrencies but am new to this specific token. Is there a specific section within the app where I need to navigate, or do I need to take additional measures? Additionally, would you recommend any particular security measures to ensure the safety of my Siacoin holdings? Your guidance would be greatly appreciated as I strive to diversify my crypto portfolio.
