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.
So let me get this straight.
Because of this 'asymmetric trading', Bitcoin is going to go up and up and up, and just keep going up, and never look back down until the halving?
erm....right.

Of course there is going to be swings and corrections, but you're not playing right. You need to have an open mind to the opposite side of the trade to make an accurate decision. It is easy to get focused on 'the chart shows this, so it MUST be going to happen this way'.
