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?
Your post looks like something that was made up, if you think back to 2011 the Nigeria currency Naira had value unlike now, if you had #100,000 back then you would be considered as a very wealthy person and that amount of money is not something that one can invest with and still be careless about it. I'm not sure what the reason you decided to create a made up story, if it's to fish merits then you're not doing well. Next time don't forget that you're talking about an online investment and in 2011 most Nigerians just take it as a scam and investing such amount of money seems unreal.
FYI Op, as long as no one gets hold of your private key they won't be able to access your account and use it for anything and also you can't recover your wallet, if anyone should come to you claiming they have a powerful system that can be used to recover your wallet just know that they're more likely to be a scam.
