It's pretty smart acutally, especially if they do a profit share based on how many of their tokens you hold.
Maybe dean doesn't want to hold the investor's bitcoin anymore so he won't have any problems incase something bad happens to him.
Token is the best to distribute easily the share of a casino, It can be also sold in the market that made the pull out of shares easily.Adaptation of Altcoin token by casino is very good and wise idea on easy profit sharing, Anyone can participate on investment even on small amount of money.
That was another way i think that can push the value of the coin fast..
Look at almost post new thread and updates every day almost ICO and altcoins thread flood daily in altcoin section every minute there are new posted about altcoin and i think altcoin is more active than bitcoin these days and casino is one of their first target to start ICO trend..
