I recently heard someone say:

when you set up a new wallet, don’t just do a test transaction in but also do one out. That means recieve and send one transaction before moving your funds to it. Is that really necessary? 🤔

If i have the seedphrase and can successfully restore the wallet after recieving a transaction, doesn’t that mean i am also able to spend? In the end it all depends on the seed, doesn’t it?
