You said you have 0.001 btc, but how did your btc balance decrease? Have you done trading? However, if your current btc balance is 0.00094 btc then the current price is $104, you are still in profit. However, plan to hold your investment for a long time, if the market is a bit dumping then don't plan to panic and sell. You always think positive and hold for a long time.
