Hi All
I had this question (probably stupid) regarding Bitcoin transactions. As you might know Xapo to Xapo or basically same Bitcoin wallet to same wallet transactions are free and off chain. So what happens if everyone uses just 1 wallet for the transactions among them. I know this case is not possible practically, but just think about it in theory. If this happens, then will Bitcoin mining become non-existent? I know I am missing out something, but just not able to get it.

Once everybody sends their coins to xapo and nobody withdraws BTC from xapo we are not going to have any transactions.
Mining will continue as you can mine even if there is nobody sending and receiving coins.
Miners will keep on getting their block reward, until this also dries up and then the whole chain might be supported by hobbyists.
Xapo will become some kind of Paypal and Bitcoin....will probably die.

Factually, xapo was a used by millions of users as a need of wallet and i remembee they hadn't fee on transactions initially but when the number of users increased, they changed their terms suddenly and perhaps xapo was first wallet who encouraged other wallet to apply higher fee on transactions. Now if everyone uses xapo, they will occassionally increase more fee

Millions? I really doubt it.
