Yes they will definitely keep the coin for a longer time. Just like in the previous ICO the investors hold their coins for a longer time and they did not sold their coins unless the price of the coin reached to more than $5 and at that price they doubled up their investment.
The investors in the previous round of the ICO really got a very good profit from their investment in the Rasputin Mansion. They got a profit when the price doubled up and many of them kept the coins till now and they got a huge profit from the dividends. Now there is a time for the next dividends which will be announced sooner.
