I invested 100$ in hashflare mining at the end of 2017. Soon after the bitcoin price started declining and is declining at the moment. In this situation hashflare has stopped giving payouts and says that the mining fees are higher than the payouts. Can anyone suggest what to do next? the following is exactly what they say.

"Dear users,
Because of the current market situation, with the latest spike of mining difficulty exceeding 14% (https://bitcoinwisdom.com/bitcoin/difficulty), while the price of Bitcoin continues to decline, the payout was lower than the maintenance fee, which resulted in the balance not increasing and remaining the same. We are considering all possible options, while taking into account the available resources, to optimize the mining process where it is possible."
