The idea of bitcoins may be fascinating for you. Nevertheless, there are some good reasons why you should under no circumstances use the digital coins as an investment or as a basis for private retirement provision.
Bitcoins do not work as a means of payment
Neither the department store nor the tax office accept Bitcoins, and most likely not your landlord either. But there are some online retailers and a few shops, for example, you can pay for food. Some organizations accept donations in Bitcoin. However, there can be no talk of broad-based acceptance. That can of course change.
Bitcoins have no material value
If you have a share in your portfolio, you are involved in a company with all of its assets. Bitcoins only have value as long as people believe in the success of the cryptocurrency. As soon as speculators turn away from Bitcoin, the value of Bitcoins can slide quickly. You risk losing everything.
