some people say greedy and some people say smart thinking
if you think that what peoples did is greedy, sell all your bitcoin or half of your bitcooin to me with a lower price..don't be a greedy

bitcoin price is very fluctuative..it can be rise $100k or more and sometime it can be down to $500, they're only take advantage from market with smart thinking in a perfect time and a brave speculation.
it's all is up to your goal...do you want take advantage from fluctuative market or do you want to hold your bitcoin and hoping bitcoin will rise?? or you want do both of them..don't forget about the risk too, because I'm sure they keep hold bitcoin with all risk to take too
