I am really so surprised with this continuing Bitcoin bull run. I am sure that a big part of the Bitcoin enthusiasts and holders are right now thinking and speculating when will this upward movement to go down. Of course, we know that nothing keeps on growing that fast forever. I should have bought Bitcoin when it was just $18K -- at that time I was thinking that it can go down back to $15K before making a great run but boy I was so wrong! Right now, I am really waiting for it to make some retracement but for the time being I will just sit down and just watch...with some sad look on my eyes.
