I'm 54 and new to Crypto. That said, I recently purchased some Bitcoins on Coinbase and want to send the entire balance to my Ledger Nano S for cold storage (retiring in 6 years); however, when I try to "send" funds using my Coinbase Wallet it says I can only send "x" amount instead of what I want, which again, would be the entire balance. All of my purchases/transactions have cleared, so I don't know why I'm limited in what I can send at one time. I can't seem to find anything on the internet, YouTube, or even Coinbase to explain why this is or how to fix it. How do I correct this issue or am I missing something? I assume my Bitcoins are safe in the "wallet" but I'm scared of losing my investment and want to put it on my Ledger Nano S for long term storage and optimum security. The idea of having to send "small" increments at a time seems like a real PITA. Please help! Thanks.
