Bitcoin is bought to sell it more expensively, and then again to buy cheaper, this so-called investment brings up to 20% per week. 
There are certainly risks, but then either losses or you need to wait

I think if a lot of companies accept btc, if btc is almost flawless (instant payment, lower cost, no security issues), I can understand that it would seem "safe" or "reassuring", which obviously did not happen.
Even long-term thinking, I can not get what makes them believe that the value of 1 btc is more than 1 euro.
Of course, the price of 1 btc is what people want to pay for it, but there must be some collateral.
