When i started to get to know about cryptocurrency I've also read about mining.. although I didn't had the special hardware I thought i should give it a try. I tried to mine a lot of different coins and it took me a lot of time..
I almost earned nothing, only like really small amounts of dollars.. and the time and the energy of the computer (and also my own energy by researching and installing etc.) costs a lot more then the little amount that i've earned.
Also it could get pretty dangerous, if you mine with a simple cumputer on your browser without he right hardware etc. your cumputer can get verry hot. And because you don't have a special airco system or something like that, your computer can get on fire.
So for me i decided that mining wasn't that succesfull. I now only do trading and i'm trying to build something on Steemit. And I must say; it is so much more fun to do this!
