Why only Look for dice game ? why not invest in casino all the way like Cryptogames.net
It's no longer cryptogames.net, the new domain is crypto.games and AFAIK, they are no longer offering an investment feature to their casino.
Actually it never was cryptogames.net ... the correct (old) domain was crypto-games.net.
And yes, investing is not available for a long time.
IMO the only remaining (trustworthy) casinos to invest in bankroll are bitvest and bustadice.
As a sidenote for those searching where to put their excesive funds I suggest to check major exchanges and their lending/staking offers.
Binance and kraken offers saving accounts with small daily interest rates.
Bitfinex, poloniex and kucoin allows also lending your funds to other traders.
I wouldn't do that if those are your suggestions. Although it's an additional source if investors want to do it but I just won't do it.
Lending and staking is not similar to bankroll investment which is more risky because exchanges are risk of getting hacked at any time.
Yes, most hackers eyes now are in exchanges.
