I would trade in all of my bitcoin because who would not trade in there Bitcoin if they see that the Bitcoin value is that high.
If you do not sell at that point then something has to be wrong with you for sure.
Yeah if anyone will not sell his coins at that price and prefer to hold then it will be an worst decision to make as I don't think that price will rise after that and it will start falling.
the price alone doesn't matter at all but instead what matters is that how that price was reached.
if it was a slow rise with real demand (like the rise so far) it will stay and you would be a fool to see in situations like these. because there will be no drop but only rise.
but if the price rise is fast and sudden without any real support like back in 2013 $1200 rise, you would be a fool not to sell. because the drop in situation like that is assured.
We never know where's the max on the graphic... The strange thing is the people that buy for this price, well, this have no whys...
Now the price sounds stable, maybe it can go up again when the next halving occour.
