This scenerio happened yearly mostly the first until midyear as i have noticed in doing my research. Most likely during the half year until before the year 2018 ends, all who are patiently waited can will rejoice because bitcoins and altcoins will be in a rocket high again. So whenever we've got extra money, then this will be the best time to buy people and see the results in few months.
I have noticed this too and it seems it is just how it is going to keep being for now and usually not only in cryptocurrency market as it seems it happens too in stocks, maybe just my imagination anyway. I guess we just have to wait and see what the year 2018 is going to bring after this huge downtrend which I am sure if the market can recover hugely after this, it should be a worthy one to wait for.
You can see that the market in recent days is fluctuating continuously and difficult to predict, bitcoin and Ethereum prices are continuously reduced in recent days and there is no sign of recovery. So I think the market is volatile and we should not invest at this point, which is extremely dangerous if the market is going down.
The market will always be difficult to predict, but for traders, they will always know how to play with the fluctuations in the market for their benefit while the holders can only have one choice which is just to hold and wait for a recovery in the market which is bound to always happen anyway. We have a highly speculative environment with a huge volatility, so I do not expect anything different.
