[New Multi-Language Exchange] Options Coin Trading + Staking Mining + New Coin Subscription + Blockchain Exchange

New multi-language exchange/option currency trading/pledge mining/new currency subscription/blockchain exchange
This set is a newly developed exchange that supports options, currency, pledge mining, new currency subscription and other functions.
The system functions are comprehensive and controllable. This set of source code also has the authorized second U function, but you need to configure the back-end contract yourself (no configuration tutorial)
The front-end browser login can automatically provoke the little fox to log in automatically. When the wallet is opened, the login is automatically authorized. For recharge, you can also authorize the recharge or manually recharge.
I did my own research and found that there are two sets of source code, one is the original version, and one is modified by someone else. The source code front-end is compiled, and there is no pure source code.
