2) What might happen on the off chance that one endeavors to send a measure of coins to an invalid Bitcoin Address?
3) What might happen on the off chance that one endeavors to send a measure of coins to a Bitcoin Address that no one claims?
I thank answerers for extending my insight.
1. You don't have to be online to receive bitcoins because the transaction is recorded in the blockchain and your wallet will see it when it goes online. In the past, bitcoins could be sent to an IP address, but that feature was disabled.
2. Your wallet checks the address to make sure that it is valid and won't try to send to an invalid address. Keep in mind that an unused address is still a valid address.
3. It is possible to send bitcoins to an unclaimed address. Bitcoins can be sent to any valid address. Bitcoins sent to an unclaimed address are lost forever.
By "unclaimed" or "unused", I mean an address for which nobody has the private key.
