Of recent flood has covered some part anf states in Nigeria and am talking based on my own experiences Port Harcourt and other areas of Rivers State and this has caused so many damages and is not just about a damaged house but it actually mean a like loss of phones, documents, cash, vehicles and other belongings that took years to build.
If you live in a region prone to flooding (or other natural disasters), should always be prepared for the possibility of a flood and plan for the worst-case scenario. At the very least, this means having a waterproof container, kept easily accessible, to store your most valuable items (such as cash, documents, and a backup phone with essential apps that mirror your primary device). This ensures that, should a flood occur, you can grab the container and quickly evacuate your home.
and he doesn’t keep any of his finincial assets in his local bank account
As you can see, keeping your money in a bank (or an exchange service - essentially, with a third party) is not always a bad decision; after all, they can safeguard your assets against factors (such as natural disasters) that you would be unable to protect against on your own.
all is funds are stored in bitcoin, in his blue wallet to be presided and according to him his phone and laptop is wiped out by this sudden unexpected flood
But what about risk diversification? Keeping all crypto assets in a single wallet? And in digital form only? Another problem could have arisen here, for instance, the failure of the storage media, which would have deprived your friend of access to his assets even without the flood.
and currently he’s stranded because he did not write down the seed phrase
This is the first rule taught when creating crypto wallets - a rule that, as you (and your friend) now realize, can't be ignored.
while creating his account he only has the screenshot of the seed phrase and password in his phone and laptop
Yet another unwise decision. It was only a matter of time before your friend lost access to the wallet. One way or another, given such negligent handling of the seed-phrase, he was bound to lose his assets - sooner or later.
If you were the one in tbis situation
I would have done everything to avoid ending up in this situation. That would have required making backups, multiple ones, given the specific risks of the region (such as flooding). For instance, keeping backups in a different region not prone to natural disasters. Even using online services, despite the criticism this option often receives, could have helped save the assets in this scenario.
Regarding the risk of flooding: water generally doesn't wash away the soil, especially the deeper layers. Therefore, to safeguard the seed-phrase (stored on a metal plate), could bury it near your home, using the house itself as a landmark, since a flood is unlikely to wash away the building's structure (assuming it is a brick house). Alternatively, you could bury it beneath the building's foundation. However, this is only advisable if the area around the house will not remain submerged for an extended period, such as in the event of a new reservoir being created, which would prevent access to the seed-phrase due to standing water over the burial site.
what do you think is the next step to do to recover your account?
In this case, there is zero chance. No backups were saved, and there is no access to them. All that remains is to acknowledge the loss and come to terms with it.
And would you be so willing thrusting bitcoin site with all your finincial assets?
I might entrust a portion of my assets, but not all of it. And in such scenarios, I repeat, entrusting one's assets to third parties turns out to be far from the worst decision.
Let me know because currently he’s looking for a solution.
His problem has no solution.
