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.
How to know that the second dividends time is coming. Did you contact to the team about getting informed about it? I was curious that when will they distribute the second round of dividends.
