For every financial venture, you should have both an entry and exit strategy.
You should read as much as you can, formulate a plan and execute it.
Your money is most valuable to you, so you should follow a strategy with safety and gain preserving strategy that you are comfortable with.
In every bull market there will be people who exit to early, and people who exit to late.
The ones who exit late, have more regrets then the ones who exit early.
A smaller profit then you could have had, beats a large loss you could have avoided, any day.
Rule number one, don't lose money.
Rule number two, don't forget rule number one.
