I believe that day trading is the best option at the moment, you can see that after two days at $ 8200 level, the current bitcoin price has dropped sharply to the $ 7800 mark, the price of altcoin are also falling very deep and set a new bottom. So if you hold at this moment will damage very heavily. The market is still bearish in the long run so I think the bitcoin price will continue to fall until 2018.
