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?
I guess there's nothing to recover back since as you said you trust your friend to create your own wallet so maybe try to check first the wallet used if the balance still intact inside since if not then maybe your friend take your money and might you cannot recover unless your friend will give a refund.
Huge mistake that you let your friend do that so next time learn to create your own wallet and never tell anyone that you have money stored their.
