Hello, There is ongoing talk about bitcoin that this bubble is going to explode soon. I learned about Bitcoin from http://technogeek.review/ and I have invested about 1.5 lakh in Bitcoins. even the same website is saying that it is going to end soon. Currently, I am in the loss, so can not even withdraw my money 
Never risk more you can afford to lose and it will be OK. It won't fall back to 0 so you have time to decide what to do with your investent
