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.
I agree with this evaluation. The drop was precipitated by the quick rise in BTC and the margin longs disappearing quickly. The consensus is that BTC is going to have a mega bull run if it breaks this wedge that's been forming for the past year to the upside. We got right to the upper limit of the wedge in a few minutes in BTC so if I was short BTC long anything else, I would be really scared. However, most whales don't need the silly margin to trade and so they technically short BTC from their own BTC holdings, but not leveraged long and do not need to sell into panic.
Personally, I think XMR will go up in value if BTC also goes up. The coin seems to be missing a few big features to get it more mainstream adoption. Friendly GUI wallet, marketing budget, and simplified instructions for non-technical people to use it. Technically, it seems superior to all other coins out there from an underlying technology standpoint.
