Is the OP serious about wanting to buy a large-scale bitcoin 5,000 BTC? because I still do not believe in a new account immediately buy Bitcoin in large quantities.
What is the correct @OmegaStarScream suggestion to buy there can already be trusted.
Its possible. Not all whale BTC holders has account here in the forum since they don't have time to chit chat here. I have many friends on telegram group chat that no account here but holding significant amount of BTC and other altcoins.
Base on what I see, if OP is legit. He might be part of group of institutional investors that want to enter in bitcoin.
And your account might have been bought by scammers and used to make them look genuine.
Any post with keywords: "remittance", "fund", "bank transfer", "serious", "secure" etc is a definite scam.
Not only - I refuse to believe that an illiterate person might buy 5000BTC/monthly... Jesus.
