The most common challenge I observe here in this community and experienced them also is over thinking. We can't help ourselves to relax in few times. The waiting is getting to our nerves yet we do our best to patiently hold on to investment.
Most common challenges are other people who do not have any knowledge of it say negative about bitcoin. Its not so sure/secure because sometimes you might lost your money in your wallet in an instant. And also other people do the panic selling so due to that the price drops continuously.
