You can check the supply distribution at stoic.foundation website. STOIC is an ERC-20 token with a maximum token supply of 4 billion STOIC.
The initial price is $1.2. Over 50% of the total token supply is to be mined by Stoic users. If you start with $1,000 and pay the $50 fee, you’re not yet eligible for receiving the STOIC reward. You would need to top up your balance and pay at least $100 in total fees. So the minimal deposit amount to qualify for STOIC tokens is $2,000 — with $100 paid in fees. Then use the formula above: 0.6 * 100 * Early Bird Coefficient.
