Those who invested in the ICO are able to sell in profit if they want.
Profit margin is shrinking. I imagine it will continue down to 2x or less. I'm curious if price will drop below ICO...good time to accumulate.
Not sure about that. I believe it could be a similar dynamic like Ethereum in it's first days. A lot of dumping when it hit the exchange but then it stabilized (above ICO-price) and then a nice rebound.
This is the Ethereum-Chart right after it launched:

To add this:
LISK has much more volume than ETH had right after Launch.
Lisk currently: 14392 BTC (not even 24 Hours)
Ethereum the first 5 days after launch:
1: 1205 BTC
2: 898 BTC
3: 718 BTC
4: 3007 BTC
5: 4690 BTC
What does that mean? First: There were also problems with ETH right after launch and if I recall it correctly there was no wallet for non-technical-user and there was a lot of complaining and there were a lot of accusations. Second: Lisk is moving faster. The times have changed and there is more money in the market now. Third: It's wanted.
Out of the perspective of those who missed the ICO all the drama and panic-dumping was (and is) a chance if they believe in Lisk in longterm.
