This is definitely a scam. I don't think that a person with 8,000 Bitcoins does not know how to get it? Of course if you are not a liar. I don't bother to help you transfer money.
He is not asking money from you,he is just asking the possible ways so we can't consider him as scammer and he may bought that 8000 bitcoins ealry stages when it maybe around $1 per btc or even lower because I know some of the people who had become millionaire from bitcoin which was received as tip in 2011.so anything is possible bro so don't call him as scammer but I doesn't look like he is active for a while so he may already chashout it.
