It's look likes custodial wallet isn't it?
That sure as hell sounds like what it is, sort of like Coinbase's "vault" feature (not sure if they still have that or not since I haven't used Coinbase in years) and Xapo for that matter.
Claims to be a top 5 wallet despite no one having heard of it and only a handful of downloads.
Glad I'm not the only one who's never heard of this thing.
And when you make a claim like this:
It is one of the five largest storage wallets in the US
when it seems like a brand new wallet or an obscure one that hasn't gained any traction, that raises all sorts of red flags in my mind.
Claims FDIC insurance with no proof.
Claims 90% ROI per year with staking.
I didn't read the links OP provided, but both of those claims are ridiculous on the face of them. FDIC isn't providing any insurance for cryptocurrency, nor is a 90% return for any staking coin reasonable. Hopefully none of the greedy suckers fall victim to this chicanery.
