It seems like the coin is not dead at all, there high activity in it's Telegram channel https://t.me/flakechain. The Russian speaking people very fond of Telegram, for some reason. And the Eastern Europeans, it seems. And asians.
Whatever, found some links there:
pool.flakechain.com
app.stocks.exchange/en/basic-trade/pair/BTC/XSF
maplechange.com/markets/xsfbtc
explorer.flakechain.com
