I think that investing in everything is risky especially bitcoin. Dont take anyones advice about what will happen with the currency. Personally I believe we are just starting, just my own opinion and you shouldnt consider that as investment advice as well.
I think Never invest more than you are able to lose Bitcoin is a very risky investment and you should keep in that in mind at all times. especially the price Bitcoin is still going down this time.
I understand your position I also never invest into anything more than I am afraid to lose. Meanwhile, I am sure BTC investments will bring us profit in 2018.
