For me the value of bitcoins comes from a few factors. The most important one is that bitcoins are the biggest crypto coin with a lot of investors. The second one is that bitcoins is known every where around the world, even children have heard about it. Another factor is that the bitcoins are limited in their number. They are independent from governments and can't just be created out of thin air. The biggest problem many of us investors have with FIAT money is that a government can just decide one day to print a lot of new money, destroying the value of the existing savings. To protect ourselves we can go into the crypto world.
