I like the estimated portion. And please put equation up for the math.
Investment / Distributed tokens = Price per token. Your investment / Price per token = Your total amount of tokens.
$53,069,235/70,000,000 = $0.7581 (Price per token). $1391 (Your investment) / $0.7581 = 1834,85 Tokens.
Does that make sense to you? This would be the calculation
without any discounts.
