It's possible to claim rewards and unstake NFTs at anytime. The maximum staking size is 12992 apecoins, we have 6502 so we'd need to buy 6490 more (19eth). Our total apecoin position would be 37eth. The monthly yield for first 3months would be: 5618 apecoins (around 16.5eth at current value), so this is 14%+ per month. The yield then decreases to 12%+ for next 3 months, then 8%+ and finally 6%+ for last 3 months. So we can revisit the position every 3 months.
