BtcWinEx is an exchange that in times of service used to give users the chance of earning while trading. There were some good transactions execut d on the platforms, and users received incomes in BTC as the service was available to offer some promotions and airdrops. Now, the site is indeed out of service. There is not way to access to the main page, as the current link is damaged.
It is difficult to know what happened to this site, bit as has been established it failed due to low support from the team. Since they did not give the right management to the page, it failed in financial activities, and now it is just recognized as a network with small features for trading.
Those pages that used to give opportunities to earn tokens were as good as those that just gave services for trading. BtcWinEx could have acted in the same way, but if users want it to be recovered, then new developers must assume to buy the network and improve it from scratch.
Note: for now, I won't give a right conclusion to this site as I hope that it can get updated. But I still advice users from keeping away from the access to this page.
