I have been doing that all 2018, I had to cash out some of my bitcoin because of some family urgency stuff and at one point I was so poor because of those things that I literally didn't know how I would eat dinner but with careful calculations I have managed to make some savings and right now I am doing much better, I both have bitcoin saved up on the corner and keep earning more and more bitcoins while not spending all the ones I have already so it means I am going to have more bitcoins the longer I keep working but at the side I also get other altcoins and airdrops and ICO's and all that which worth really not that much right now but I believe they will be one day which will make me super rich (hopefully). So I definitely agree with this post and believe bitcoin will be not only over 6 thousand dollars but will be over 10 thousand one day.
