You have a lot of competitors, so for success, everything must be done at the highest level. I think such a platform will quickly become recognizable, but people will stay only if the technical implementation does not fail.
who are their competitiors? Is there any other project similar to the Egold? I don't think that there is other project that have got blockchain technology, cryptocurrencies and bets at the same time
All of them are listed in the project description. There are quite a few such platforms, but eGold seems to be the most ambitious of them.
