Is there any cap on the maximum amount to get from each wallet linked? like one BTC max for each wallet or how many bitcoins we have in our account will get same amount airdrops?
Secondly now when I open wallet asking for an upgrade to a newer version but in my wallet now have already coins. Do I need to move my coins to another wallet before upgrading or I can just upgrade it?
Thanks for your time...
To be clear on a response you received...
The cap is the number of bitcoin in existence.

Upgrade the app. It is stored in a different directory than your wallet. So, it isn't touched. You will not get a new wallet simply from upgrading. Now, with that said, you should always backup your wallet.
