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.
I wish I can get a better word than fruitful and extremely fruitful most especially for the traders. I know it has been a tough ride, but the truth is anyone who bought at the top and decided to hold should have also taken this opportunity to start buying at the bottom. No one can know exactly what would happen at any point in time but with the help of some technical analysis, one should always get better in the long run in earning some pretty good profit.
Yeah buying at this point should at least even out your losses a little once the bears are done with their patrying. Everyone would prefer to have a mostly bullish market all year round but we can't forsee certain things like what's happening now with mt.gox dumping.
