Your priority when buying SafeMoon, just like any other digital currency, or even any other asset, is to do so safely. After all, you're working with hard-earned money, and there are a lot of financial risks right now. Therefore, reducing risks and buying digital currencies safely is your top priority.
The best thing you can do is go for customized platforms. Most major exchanges are configured. Bitunivex can also be a good option. Another thing to keep in mind is that you should transfer your SafeMoon to one of the SafeMoon wallets after purchase. Withdrawing your coins from an exchange to SafeMoon wallets makes you the sole owner and manager of your coins, meaning they will be as safe as they can be, provided you know how to keep your wallet safe.
