I hereby make a public bet that whatever amount you invest into bitcoin today (21-December-2017) will double in value within 6 months - That is 22-June-2018.
I will revisit this post and put myself to hall of fame or shame depending on the outcome.
Current price of bitcoin - 21-December-2017 - 17,000 US Dollars
Predicted price of bitcoin - 22-June-2018 - 35,000 US Dollars.
Misconception #1
You need 17,000 US dollars to buy a bitcoin. you can buy 0.1 or 0.01, or 0.001 or whatever small amount you want. even as small as 100 dollars.
