till today i never invested in bitcoin because i dont know why i dont invested 
i thought to invest last month but unfortunatly i not invested at that time the price of bitcoin is 63K INR ( around 970$) and now the price of bitcoin was rise like indias population 117618 INR ( almost 1828) i am feeling very bad for now. 
but still i suggest you to not invest all your money in bitcoin .
It is a regretful moment for you to not invest in bitcoin because if i were you and i see that price then i will invest immediately because if ever the price of bitcoin goes down i will just hold my bitcoins and wait for the price to pump again and sell it for a higher price. You can still invest your money now in bitcoin but just what like you said, do not put all your money. i thought to invest last month but unfortunatly i not invested at that time the price of bitcoin is 63K INR ( around 970$) and now the price of bitcoin was rise like indias population 117618 INR ( almost 1828) i am feeling very bad for now. but still i suggest you to not invest all your money in bitcoin .
