Few years ago I got into a bitcoin mining. Then, it was still a beginning and a nice amount of money could be earned over a month. There was a big jump in value, mining wasn’t so profitable anymore (at least not with a single PC), I waited to sell but soon a bubble bursted and the value dropped significantly. I managed to get out in time but now the value is stable for some time so I am wondering if I made a right choice. Do you see a potential for digital currencies, namely bitcoin to disrupt the online payments space?
