If you just keep them in your wallet for 2 years, price will increase that much that you will not even think of moving all in one go.

My aim is not to dump. Actually, my aim is to help create real liquidity for XMR. As you may have noticed, you can't buy or sell more than a few BTC worth of XMR without moving the price 10%. I plan to change that by putting up more bids and asks closer to the spot price. That's why I need to move my coins.
EDIT: I have cooled down now. Poloniex can have another chance.
I would be wiling to add liquidity to Poloniex, how can I help?
