sell in May and go away!
What are your price assumptions for summer 2019?
I will not deny the reality that bitcoin do perform badly in August and September in most of the years but it seems this year is going to be different as bitcoin seems to be relentless in it current bullish trend. More positive news and information has been flowing into the market this days and because of those information I strongly believe that bitcoin is going to remain above $10,000 once it get there. The expectation of what is going to happen after bitcoin halving by next year is also one of the reasons why bitcoin should grow throughout the remaining days of this year.
Yes, Bitcoin usually perform badly in the months you mentioned and during the Q4 in most years but if we compare the status of the price of the previous years of Bitcoin when it halving will happen next following year the market are usually in slightly bullish trend. However, we all have different purpose but selling now or the months you mentioned is not a good decision.
