I find the current trend is to hold coin worth, trading habits should change because it is really complicated and difficult to bring profit, stay away from the ponzi model and lending ico. That is my advice, and you, see the current trend like? 
Indeed, investing in ICO projects will be a sure and profitable investment. But we can also exploit Bitcoin. Bitcoin's current price is $ 8k and that number will certainly be profitable for those who invest in Bitcoin. I think Bitcoin's prices will remain at this price until 2020. We still have two years to exploit Bitcoin before things go down.
