I still made money when the bitcoin price was still about $6,000 on the beginning of last month. After the price of bitcoin decreased, I didn't make money yet. I have coins paired with bitcoin, so my income depends on the price of bitcoin.
Well this is called making the right move in the right time. The most good you are at the market signals and smelling profits, the more profit you would earn. In addition, one should also keep an eye on the emerging good icos.
