They claimed the total deposit is 256778.51367054 BTC, but when I checked their deposit address
1NPJdrF5z1DidXuyn3XRSoPu9GYNS3rHDF Total Received 0.07733467 BTC. Means most probably they already scammed that amount and moved that funds to another wallet. They are showing a few fake random transactions on the homepage, they just collect that from the blockchain. How stupid they are, even included change address's with total withdrawal they are showing on the homepage.
So it could be that they manipulate with the amount of bitcoin more people have more confidence that has been deposited a lot or also the funds have been transferred it could also be, but what is clear is that they will not get that large amount of funds, I just think that's more number manipulation.
Bitcoin doubler is not correct. It's all a scam if someone deposits it it can't be returned, so they made it like this because of the current bullrun situation.
Hopefully there are no more victims in this double site.
