I don't want to upset you, but I think that in December there will be no pamp (such as was in 2017). For several months everyone has been repeating that in December there will be a pamp, everyone believes it in a holy way. I think that it will not be for this pamp, everyone hopes too much for it. Maybe sooner or later, but not in December.
I just like you all hope that soon bitcoin will begin its growth. Everyone expected that in the middle of August there will be an ETF, but it was postponed to September. The market is sad again ... Let's see what will happen in September, and then we will discuss what awaits us in December.
I believe that there will be no big increase in bitcoin prices, and you can see that the current market is volatile and unpredictable, bitcoin prices are constantly adjusting and changing. I believe that the market will continue to decline and bitcoin prices may fall sharply by the end of 2018 so you should only invest in short-term bitcoin.
