Lets say I want to send 0.05 BTC from my Coinbase wallet to my friend who has a Bitpay wallet. Will this show up on the blockchain as one transaction with one input (my public address) and one output (friend's public address)?
That will probably come up as multiple inputs (
from Coinbase's Hot wallet) and multiple outputs (
to your friend and other users).
Because Coinbase isn't a wallet and they might process withdrawals in batch like other Exchanges do.
IDK if they implemented it already though, 'coz I stopped using their service years ago. (
Their statement that mentioned batching: blog.coinbase.com)
