Early 2011 most friends of mine are into cryptosystem and I barely know what it is about, I only hear the name bitcoin and one day a friend of mine said, I should provide N100k to buy bitcoin and I was like what if my money lost and he gave me assurance; no lost as long your wallet is intact and after much pressure I gave him the money, open a wallet for me and hand over everything but I was care free not minding that's a great investment then, one day I lost my device and that's how I lost the seed phase and the wallet. Am imagining if I could have recover my wallet today, I will be a big boy with fat wallet. Do you think another person have access to it?
Though the story mostly looks like a made-up story like a lot of people already said, I would say that one can literally not be carefree after investing an amount that makes a difference in their life, and back in 2011, the value of money was way higher than it is right now, so you are pretending like you were either too rich at that time or you didn't really invest that much money in Bitcoin and then didn't make backups of your wallet, seed phrase, and private keys.
There is definitely no chance for you to recover your wallet if you don't have anything that takes you back to your wallet, you don't even have the public address, I assume, if you had really bought Bitcoins, they are now lost and there is no one who has access to them as they are encrypted.
