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?
Sorry for your loss. Your friend that introduced you to bitcoin did not give you all the information you need to keep your bitcoin safe. And you were also ignorant because you would have carried out your research before investing such a high amount. As others have indicated, you have to way back up your seed phrase immediately after you create a wallet. But I am glad you have learned from your past mistake.
I am a Nigerian and I know how Nigerians behave. And as at 2011, the value of N100k was very high that it could buy you a plot of land in some mini cities. There is no how you will invest N100k by then as a Nigerian and became carefree about it.
By that time you mentioned, it is only a few people that could invest more than N10k in an online business they consider a ponzi scheme. I am sorry, I do not believe your story.
I doubt if you know how everybody in Nigeria behaves. Investing in a particular area is by choice. So many people might not have an interest in real estate but prefer the crypto sector. Some people can also be stupidly carefree with important issues. It is true that many people even to date see bitcoin as a Ponzi scheme but I know few persons that took advantage of the opportunities the sector offers.
