I just really do not know about selling.

At some point, there will just be no buying back in.
I know it is coming, but i let myself get too scared to accurately predict it.
I can see all the dominoes stacked up... the demolishing of on-ramps and off-ramps.
Dollar pegged coins showing too much signs of scammi-ness....

I know the highs and lows of bitcoin... but just have to ride them... HODL
because my fears do not let me trade the down side.

And i am unsure it is the bitcoin-halving but that the halving happens at a market-timing-pace. So, you end up with much more affect from the market, but the only real indicator people are looking at is the halving.
