Bitcoiners want to get billionaires quick with their little scheme, call noobs that are trying to get out of the mess late "greedy".
It is no secret that I sold some at $675 in 2013. The next exit zone starts earliest at $3,000, probably higher.
It is no greed to sell at a bottom, it is just stupid. Stuff is as valuable as a year ago (or more, due to more adoption, etc.), yet 75% cheaper. This is a game and you are offered 4 times better odds than last time when you took them. Instead of taking them now, or holding, you decide to fold.
If anyone becomes a billionaire with bitcoin, he deserves it. So many chances of folding were offered but he held on.
If a person had sold when you infamously called the bottom months ago at $500, they could buy back in now and almost triple their holdings. So good call there.
And I'm not sure what you mean by "adoption". Many people have sold their holdings for a loss and left the game, probably for good. More retailers are accepting bitcoins, but that's not adoption. They're merely accepting bitcoins through a third party processor to dump to USD immediately... and the only reason most of them are doing that much is because bitcoin cultists begged them to integrate bitcoin payments. From a marketing standpoint, that makes sense. But it doesn't mean retailers are embracing it.
In fact, I think it's a negative direction for bitcoin, since it shows that retailers cannot take the risk to hold such a volatile, hackable currency and instead prefer to dump it straight away. This is not progress, it's actually a proof of concept that bitcoin is not functional as a real currency.
