BitBays is NOT BitBay.
BitBays is a BTC and LSK exchange.
We have been operating since 2014 and continue to operate: we've released our iPhone and Android wallet app and recently started supporting LSK trading.
We have offered interest for on-platform assets as a promotion. While that promotion has ended, we still offer our BitBays Arbitrage Fund (BBAF) where you can invest and choose what currency your money is held in: USD, RMB, BTC. Returns are around 10-12%. We have been arbitraging since 2013 and our 24/7 arbitrage trading bot does better than most.
We've never been hacked, we've never lost bitcoins. We've really built out our business in China - so if you searched for us on the 'Chinese internet" (币贝网 or 比特湾) or followed our WeChat account you would see we are quite active, and engaged with a number of our clients.
If you have any questions about our platform, I'll gladly answer them.
