The reasoning behind the usage of CLAM is because the amount of BTC was too high back in the days. What CLAM actually does is introduce exchange rate risks for players and investors. Because who are we kidding? How many players and investors are actually using their own CLAM instead of exchanging them.
CLAM prices ten-folded after the re-opening of JD. I don't know if there were any events beside that, but looking at the history of CLAMs exchange rate, it seems pretty obvious that JD played a huge role here.
So the only thing that's keeping players/investors back is CLAMs uncertain future. If that was the plan, then it will prolly work to some extent.
The reason for going to CLAM, as far as I understand, is that it isn't easily converted to fiat yet
But when it will dooglus will not close Just-Dice.
CLAM was a way to reopen without doing a bitcoin dice.
