There are many speculations about the market and different people make different speculations so you should never get influenced by someone else's thinking, it's your sole decision to make. And from what I believe bitcoin is gonna rise for sure and it's also same as that of stock market, that there are 3 movements in the stock market, first is bullish, second is bearish and third is constant. So the same is also applicable in crypto market and right now we are in bearish market and in the end of 2017 we were watching bullish market, so we should wait for another opportunity like that. What you can do right now is that you should buy some bitcoins with any extra money that you have and wait for a bullish market.
