I wouldn't consider bitcoin as a "safe" heaven, but the alternatives have turned sour in the last few days/months...
Gold and silver are down
stocks just took a beating (2008 in the making ?)
fiat is being constantly inflated
commodities are up but for investing
so probably a lot of investors are getting out of the stock market at the moment and while they won't go all in we may see some now money testing the waters over the next few weeks.
Well, we know at least the security part of BTC is safe. The unsafe parts lie at the users level and of course in a bigger way at the government level.
Regarding that last point, look at what is happening to currencies all over the world. Essentially we have "managed" hyperinflation! Confidence is all that is keeping the system up. If a few more
stock market crashes happen like in Japan today, this ship can topple and that lack of confidence would just open up the flood gates to Bitcoin and other stores of value (see Cyprus - I spelled it right this time, please note). Now, in that way, what do you have to lose? (A government closing it down? A price crash?
) You need some store of wealth. Gold and Silver work but the banks and/or hedge funds have been naked short selling them and you can be sure that will continue as they do not want people to lose confidence in the Dollar, Euro, etc.
But people are still buying them up. So, safe to me is a relative thing. The whole reason why
BTC is here right now.
When the stock markets start crashing the currencies will be right behind them (maybe not in that order) and then you will see a disconnect between dollars/Euros/etc. and gold/silver/btc. You will want to be holding something in your control, not a governments or states or military's.
