you would have had to have been very, very good, to have played that pump long....I suspect most that piled in, either piled back out at a loss, and/or are sitting right now biting their nails

Do you know what the word asymmetric trade means?  It means whoever goes long right now, even if it did drop back to 420 by some miracle (not likely), they wouldn't lose a dime because you can easily just hold the long until halving rise is over and still be in mega profit.  That is who you are trading against and why you lost.
