Where can I buy Nexo?

Could you please elaborate on the various avenues for acquiring Nexo tokens? I'm particularly interested in knowing which cryptocurrency exchanges offer trading pairs for Nexo and whether there are any direct purchase options available. Additionally, I'd like to inquire about the security measures and reputation of these platforms to ensure a safe and reliable transaction. Furthermore, is there a minimum investment required or any other relevant details I should be aware of before making a purchase? Your insight would be greatly appreciated.
