a good way to increase bitcoin but you really need to be a day trader and you need to allocate a lot of time when you will do this type of increasing bitcoins. Because there are times that the selling rate is low and you don't have choice to wait for it to become higher upon selling. You can try to market your own skills there and try to find the right person who really needs your service, it just depends on how you are going to market yourself.
It will happen to every job. Because the more we focus on a job then we can get the best results. Focus on one job, never incriminate our minds for uncertain things.
