Taking out BTC with the least tax as possible

It's been over a year since my last purchase of BTC, so I won't be paying capital gains taxes for investments that are less than a year old. However, I need a good amount of money to buy something in the near future, and I can't take out a loan as my income isn't high enough. So, my only option is selling some BTC.

What's the best way to go about this? I was thinking of taking out some BTC little by little throughout the years, to pay the least capital tax possible while also letting the BTC grow at the same time.
