People new to Bitcoin may want to consider the 3 Bitcoin Rule (3% of total), since investors unfamiliar with Bitcoin have many stories involving mistakes of selling too early, or jumping in at the wrong time due to the panic of missing a trend.  I met one of the smartest bitcoinaires at a meetup in downtown Dallas, who interacted with Satoshi on the bitcoin forums and was one of the earliest adopters.  He sold his bitcoins to pay for student loans and felt regret at selling the too early, even though I would argue he made a good trade. However, seller’s remorse can happen and we can mitigate it by simply following this 3 Bitcoin Rule: always keep a minimum of 3% of your bitcoin total (so 3 if you have 100).  In our minds, we’ve “lost” these forever, so we don’t debate whether we made a mistake when we sold some or not.

Traders who have more experience may find this rule inappropriate, but for people new to bitcoin, this has done well over time.
