As an early member, I have about 5,000 Tezos. By the way, I have a private Key but I haven't moved my coin to my wallet. How can I move it? please answer me.
I would recommend you use Kukai as a standalone app (preferably on an clean computer or bootable usb OS) and then move your coin to a hardware wallet like trezor or ledger nano s or x. After that, you should ideally delegate or bake to participate with the tez community and earn staking rewards.
