I was told by support once..... that the investment would not be affected by the rise and fall of BTC as it is disconnected from the balance:

It was our intention to remove the bitcoin volatility from our investment plans and therefore decided to keep all account balances in USD. This eliminates the risk that earnings are wiped away in case of a bitcoin depreciation.

Now if you invest with bitcoin, the only risk you are facing is the period of time between the purchase of bitcoin and depostiing them with us and vice versa once from the moment you receive your cashout until the time you are able to liquidated the coins into fiat. However, both can easily be managed by picking a day when the volatility is very low.

Please let us know if we can be of further assistance.

With best regards,
