I already have some amount invested, but way less than I'd like to have, but I have that fear of being put on risk more than I should.
How it's even make sense to invest more when you're not even confident with the current money you've invested?
Only invest what you can afford to lose, if you feel an emotion, it's better to reduce the amount you invested. If you still worried, it's better if you learn about Bitcoin and find a good reason to trust it.
