No one can predict the price of coins on the market. There will be lots of opinions and predictions, but I am sure the best decision is in you and your knowledge. Maybe you can divide your investment in two terms, long term investement and short term investment.
At first it is better to choose one over the other based on your personality and your abilities, I say this because mastering the market is something that is incredibly difficult to do and being good at just one form of investment is already very difficult and many people never manage to become successful at one of those options so it is better to focus only in one.
