PM me for reason.
Let me guess: taxes? Claiming capital gains while in reality you got the coins in other ways?
As attractive as this offer sounds, I wouldn't dare risk money laundering charges because of this.I think it is probably more likely that the bitcoin being exchanged can be traced back to a theft or hack. There is no reason to need to prove you held coin for 4 years to pay long term capital gains tax rates. You also do not need to provide that level of documentation when filing your taxes, at least in the US, and assuming you are not being audited (audit rates are very low, and I have no idea what level of documentation would be needed in the event of an audit).
I think if anyone were to deal with the OP, they will end up having many merchants and exchanges be unwilling to accept their coin.
I would be willing to deposit + withdraw them from bitfinex or binance to prove that they are not stolen./blacklisted
As I wrote in the post there could be also other people interested in this who only need 1 year aged coins.
