Its a good plan mate and I hope you won't sell because there will be halving in the next couple of years so holding till 2020 is a good idea. Because when the halving occurs, bitcoin will be more scare so the price will soon reaches new ATH and if you buy it low and hold on it, you are definitely in for a good profit run yourself. I hope you can stick your plan mate and no circumstances will force you to sell your bitcoin.
