You predicting that the price of bitcoin will double? What time frame? We're still farther away from the $6000 mark and we have to overcome a lot of hurdles to even touch $5000 at this point. I would just advise everyone just to be cautious but if you're a risk taker, then go for it, the price looks cheap and a perfect opportunity to accumulate before the next bull run happen in 2019-2020.
