Thank you for the detailed explanation! If it isn't obvious that I'm new to this, it will become evident shortly.  I sincerely appreciate your patience in advance.

I recently purchased some LTC via Coinbase to start learning the process, industry, exchanges, etc. It wasn't motivated by this Litecoin Cash announcement, so this LCC interruption to my learning is a 'deep end of the pool' exercise for me, hoping I don't f*$k it up.

I installed the official Litecoin Core wallet and 'sent' LTC from Coinbase to my LTC Core wallet, and then back to Coinbase. Everything worked and I felt a little more confident that I could still learn stuff. I purchased a little more LTC from Coinbase then moved it to the Coinbase Vault. I don't have access to private keys in the Coinbase Vault but can move it to a wallet after a 48-hour request delay (for security reasons). Based on the recent fork block estimates, I don't have 48 hours available to get my coins moveable before the LCC forks. Are my purchases and movements already in the blockchain sufficient to claim the LCC when it forks or am I screwed? If screwed, then I've learned, I will still have my LTC, and it hopefully won't turn into a missed opportunity to retire early (not that I don't wish all of you the best!  ) Thanks for any input/responses.
