i think the reason behind this is that, a lot of the who sold their bitcoins are new to investing, it seems that they do not know what to do in times we there are bad news going around, and i believe they also lack trust on bitcoins, since just a word from jpmorgan's jamie dimon, a lot already sold their bitcoins and instead of holding them and looking at the gains that they could possibly have by now, i think they might be regretting that decision they had made, but all is for the better, i hope they already learned their lessons and if they want to invest in bitcoin they may do so, but they should really come up with a plan, not just selling their bitcoins. it is also a good thing, since now we know, what percentage of bitcoin users are actually knowledgeable in what they are doing and not jut going with the flow or following the trend since bitcoin's value is going up.
That is what you called weak hands. There are countless advises here in the forum telling newbies not to sell because it won't covered their losses. But still they immediately panic reading a lot of FUD here. And it will hurt them. Hard lessons to swallow. All you have to do is just be patience and stay calm and don't be nervous or disappointed when you see that the price is plummeting. I hope they already learn this painful lesson not to panic otherwise they will just lose their hard earn investments.
