Don't worry, now that it's already come down this far, you might as well hodl on and see what happens next. In the future, be careful about anything that seems too good to be true, and always diversify. A very important thing to remember in investing is to never let the emotions get to you and control your actions; don't panic sell because you're scared or regret your decision; instead, make a well-informed decision. May I wish you best of luck on your investments.
