I came across this news on CNBC where standard chartered bank claims that bitcoin will reach 5000$. Being a bank, this can be their wish and not a reality. Banks do not want bitcoin to become popular and therefore they spread this negative information so people panic sell and do not adopt bitcoin. 
What else do you expect? Banks and Bitcoin are not friends so it's normal that they won't help it to become popular. By the time BTC came out, banks are in fact in a critical position and im afraid that they will lose their fame pretty soon. No need to help BTC but their own self are the ones that they must help to retain their position in the financial industry.A bank that gives a statement about BTC doesn't make BTC become less popular but it will actually help BTC to become more popular because they are exposing it or advertising it indirectly. People who aren't yet into BTC, will be curious and might end up trying and liking it. Telling that BTC will drop won't also cause a FUD but it will only help people to get excited of buying it.
