Bitcoin can be a safe heaven asset?

[MasterFx]

Well, I am still concerned about if BTC can be a safe heaven asset, because of its huge volatility. Also since is concentrated in a few hands it can be manipulated. Also the lack of solid rules, so we don´t know how vulnerable is.On the other hand, the great acceptance by big companies like Facebook, Telegram and many others increase the number of people that accept such cripto assets.
