What we saw this weekend was not a whale dumping, it was the unwinding of Monero margin long positions, triggered by a $10 rise in BTC which spooked the longs into selling. Yes, there were a lot of Monero shorts open, but there were probably even more longs, as various traders were gambling on the price movement.
The initial BTC rise spooked some traders into dumping their margin long, and the drop put others into margin calls and they sold as well, and it continued down to 321k, at which point pretty much everyone with a risky margin position had dumped already.
Monero performed worse in the 'altcoin crash' that some of the other alts because it had more margin long positions open than them, due to recent price rises and bullishness, so once the panic selling started, it had more selling pressure.
This does not imply that Monero whales were dumping. It does not make sense that Risto or some other Monero whale who has a lot of btc would panic at a $10 btc rise, and dump his Monero. It makes complete sense that some daytraders, or should I say gamblers, who were betting on Monero were put into margin call territory and panic sold. Complaining that the monero whales do not protect the little folks and dump on them is incorrect.
We have unloaded a bunch of margin longs and traders from the Monero train now. It also seems that we got a lot of shorts out of Monero as well, so deleveraging has occurred.
The coin is not 'in the wrong hands', and we do not 'need zcash', which is an absurd comment because zcash is a premine while Monero is a fair distribution, and all of the Monero holders either paid for it or mined for it, and do not have coins that they can dump at any price and still profit.
Plausible theory. By the way, the guy whos stated assumptions you are responding to is just trolling I think. I believe Monero has a very diverse distribution which gets more diverse with every "Whale Dump" as the troll called it.
