2017 was a very fruitful year for a lot of Bitcoiners. However given the stability of Bitcoin it is very hard to project plans that's too far ahead. For me I would check the trends every now and then to keep up with the rise and dips of the price. If it dips, I will try to get more and if it rises I will sell. I see no use in hoarding it anyway. Being too clingy might have negative impact suppose the price dips for good. Better safe than sorry.
