Here are some additional aspects of Bitcoin that can be challenging for new users:

• Security - Securing Bitcoin private keys is one of the most important but difficult lessons for newcomers. Many new users lose or have their Bitcoin stolen due to poor security practices.

• Volatility - The price of Bitcoin fluctuates wildly, much more so than traditional assets. Users need to understand that Bitcoin is a highly speculative and risky investment.

• Anonymity - While Bitcoin transactions are pseudonymous, tracing coins can reveal people's identities. New users are often unaware of anonymity limitations.

• Irreversibility - Once a Bitcoin transaction is sent, it cannot be reversed or cancelled. New users often make mistakes that result in lost funds.

• Scalability - The Bitcoin blockchain has limitations that make it relatively slow and expensive to use. Layer 2 solutions can be complex to understand.

• Regulation - Bitcoin exists in a somewhat grey regulatory area. Many countries do not have clear stances on how Bitcoin should be treated and taxed.

• Scams - New users are particularly susceptible to falling victim to Bitcoin-related scams and fraud. Common schemes include fake ICOs, Ponzi schemes, and hacks.

• Forks - As mentioned earlier, forks can be confusing for new users. They need to understand how forks affect their coins and which version to support.

In general, many Bitcoin concepts, terminologies and technical aspects present challenges that new users have to overcome. While the innovation behind Bitcoin is immense, the learning curve for newcomers remains steep. Becoming well-versed enough to use Bitcoin safely and effectively requires time, effort and guidance.
