There is a new interesting token coming soon, called $MWIN by Metawin. I think it will be a serious opportunity and a successful token compared to other casino tokens that exist today. If I were you, I would keep an eye on $MWIN.
Of all casino tokens, The FUN token looks the least tempting for investing. It's my opinion... I may be wrong, but everyone should do their own research before investing.
Betfury's token doesn't look any good to me. Their APY reward for BFG stacking is exceptionally high, I don't think it will do any good to them because they have to pay money to users who stack BFG, 50% and higher APYs are no joke for casino to pay. The only way for them to pay this amount of money is to make the coin less valuable. The only reason why coin will rise will be that high APY will attract new customers to put lots of money but then, they'll be forced to inflate the coin in order to pay the interest.
Freebitco has being the only platform promoting FUN token, but right now, they already have issues and users are already leaving that platform, if they close down, I fear FUN token will turn to another failed project and might even be among the next set of tokens Binance will delist.
Besides freebitco, club riches and Dplay promote fun token too.
