I've been seeing bitcoin suffered from holidays a lot and there is a proper explanation on this, since yearly it always happen.
First of all since December - January are the most anticipated holiday of all months the moment we hit BER months crypto are more likely to suffer since most of the traders are converting their assets into fiat which only leads to a massive fall of crypto, no matter whats upcoming event is or any news regarding cryptocurrencies it always seems to fall in the 4th Quarter of the year specially on December, it cannot be prevented so as a holder it is better to let go of your assets before the fall happens September and October are the best month to start analyzing the price.
If you convert or sold your crypto into fiat you're contributing in the massive fall but if you don't you'll lose the price you currently have so what else can you do.
Its been 1 year where the market in crypto was became crucials in every exchange platform. Perhaps in 2019 it could be the beginning of bouncing its price value in the market as well. Where I know mos of the community in this industry are also expecting it to be happen. So for now, it is rather good to hold our coins for awhile as long as the market is down.
I do also believe that 2019 will going to be the year of crypto bounce in terms of price since the last quarter of this 2018 sucks at the moment although its 2 weeks more before come to end. Holding coins is a must now when you don't want to lose and hope for another time but if there are circumstances that will force you to withdraw from crypto then go.
