so far no big investors say bitcoin is not safe many I have met say bitcoin is not safe only people who want bitcoin to fall they create ways or fake news to drop bitcoin price. so if the question is bitcoin a safe place, the answer is bitcoin is really a safe place.
Many big investor in the past having said that Bitcoin is just like a bubble, Once this bubble boom you don't have anything in your hand. If BTC is the safe haven then Chinese would definitely fill up their bags. What you say is BTC backed by US government or Elon musk 
Why do you say that as if there is still no belief in bitcoin's growth so far.
Do you doubt bitcoin because the current bitcoin price seems like an unclear bubble.
It's true that bitcoin so far has not had great support from the US government, but hasn't bitcoin already had a push from Elon Musk?
