Going all in

I’m about to start this journey. I got my yearly bonus and I put it all into BTC. That went into a cold wallet. I left enough in Coinbase so I can use their debit card to pay for my day to day expenses. If there are any bills that need to be paid via ach I’ll sell and then transfer it. If BTC crashes I’ll still have enough money to recover in the cold wallet. My paycheck is going to be direct deposited into Coinbase.

What am I missing? What recommendations do you have?
