Bitcoin is suitable for save value and escape of controlling from government. It cannot replace Fiat.
But I hope it will rise to 500k in decade.
It will be very much interesting to see the market value of the bitcoin as well as rest of the crypto coins after ten years or so. I am very much hopeful that by that time, the market value of all the crypto coins will be much higher and that there will be so many investors who will then be investing their money into the crypto coins and we can also hope for the legalization of the crypto currencies as well by that time.
