Went to buy some btc to my usual guy and i acquired new phone with blockchain wallet got my coins transferred and didn't set a password while i was returning home i realised i missed my pin and i don't know it Is there any chance i could retrieve the pin ?
That's one long ass sentence. Do you mean your pin for your blockchain wallet? Did you not set a pin? I don't even remember having a pin when I had a blockchain wallet. Send them a support ticket
