Only buy #Bitcoin with money you don't need in the short term (eg. don't buy with your rent money).

Build an emergency fund with 3-12 months of expenses so you can avoid being forced to sell if you lose your job or face an unexpected expense.

You can buy small fractions of BTC over time if that's what you prefer.

Ignore the people telling you to get to a 100% Bitcoin allocation - they don't know your financial situation.

I think Bitcoin is the future but I still have a primary residence and a tiny bit of gold for the chance of a complete system collapse.

I think a worse position to be in is selling in a panic because you can't handle the volatility.

Don't put yourself in a situation where you have to sell when the market price is down 50%.

Your emergency fund will let you avoid selling right in the middle of a bull market.
