Now it is already more than one week and you may need to wait for some more time to see this implemented. Why do you want to play with the only burst? If you want cheaper coins then you can choose dogecoin for time being right?
Well, that's his choise to play with only burst coin or not but can't understand if it really matters because no big difference if main idea is profit because betting system is nearly similar.
people usually choose some altcoins because they have more of them. i don't know if this is really the case with this user or not but mostly for example people get the altcoins in general from airdrops, giveaways, sometimes even from signature campaigns, and obviously a lot from mining and want to gamble with them to have the fun of gambling and possibly multiply them.
