you cannot tell what will be the price tomorrow and the market is cannot be predict unless you are a rich person so you can dictate the that you want but if you don't have any large amount of money then you will have a high risk in doing investment in bitcoin. All the investments are risky and same is the case with bitcoins to as we cannot afford to trust bitcoins blindly
The amount of money you have does not dictate whether or not you are able to predict the market, while there are some people that are able to do it, you need to understand they have dedicated their live to do exactly that, and unless you are prepared to do the same the truth is you will never be able to do it and should be happy to just invest long term.
