I think the old adage remains in full force: Don't spend more on Bitcoin than you are prepared to lose. I didn't confuse "spend" with "invest".
If for some reason I had $8000 burning a hole in my pocket, I most assuredly would NOT spend it all on Bitcoin. To me, $8000 is not money I am willing to lose at this time. Of course maybe you just won the lottery!
Good post and I your last sentence is bang on. If I had $8000 it would stay as $8000. I certainly would not buy bitcoin or mining equipment at this present time.
