When a coin is just launched there is no market, no exchange, and no price. If you want to buy some coins before they are sold on any exchange, how do you estimate the price? Here is a formula from Alvin Lee:

(Total BTC Supply ÷ Total Altcoin Supply) ÷ 5000to10000

It worked out well for Pandacoin: (21M÷100000M)÷5000to10000 = 42to21 Satoshi. A few hours after the start chaos you could buy it at 48 Satoshi. So the price of the magic formula was a good price before it was available on Cryptorush.in.

Same formula but slightly different written:

21million / “Total Altcoin Supply” / 5000 = optimistic upper valuation

This gives you a starting point for trading altcoins pre-exchange. Also, coin developers take note: This is also the price you should try to get for your coins initially.
