Guys is there any trusted casino which accept erc20 token?
I mean not only top crypto currency. Some of the oher tokens in second part of crypto tables
Most likely not.
Basically ERC20 tokens are generally only used for speculation of the underlying ICO. They are generally sent to and from exchanges and when the mainnet of the underlying coin finally launches, they are later converted into their native coin and might be used for services, however at the moment not many of these coins are used.
Primedice just introduced some upcoming service where they will use a 3rd party exchange to broker into their dice site, so maybe that 3rd party exchange will be able to accept your ERC20 token.
But at the moment I don't think there are many sites which support this. Your best bet is to sell the ERC20 for ETH or BTC and use that to gamble and then just buy back the ERC20 token.
