Let's assume the year is 2025 and we have an $8T market cap (WEF survey estimate). What percentage of that will Chainlink control, and how many tokens will be in circulation?
Let's say 5%. I think that's a pretty reasonable number. NoLinkers will argue 1% or less, Linkers will argue 10% or more. At the end of the day Chainlink will allow legacy infrastructure to interact with things on the blockchain and allow for smart contracts to take inputs and outputs. I think we can all agree this is a very significant ability that will bring crypto towards mass adoption.
Let's also assume that there are now 500MM tokens in circulation. We honestly have no way of knowing how many there will actually be, but let's make it 50/50.
$8,000,000,000,000 * 0.05 = $400,000,000,000 / 500,000,000 = $800/LINK.
Now the $8T figure (10% of global GDP on the blockchain) proposed by the WEF is considered a rational valuation... what if we form another bubble before we reach that? This makes AB's $10T-20T target seem much more realistic. Obviously it won't last forever, but it will help us find what Chainlink could reach at a possible ATH. $800 * 1.25 = $1,000 & $800 * 2.5 = $2,000.
In summary: A reasonable estimate for Chainlink's price by 2025 is $800 per token with an ATH of $1,000 - $2,000. Run the numbers again using different figures if you wish, but I think I was being pretty fair. Even when using 1 billion tokens in this estimate, someone holding just 2,500 LINK would become a millionaire. Take a moment and multiply your stack by $800, $1000, $2000, heck even $400 if you want a worst-case scenario. Be sure to remember those numbers when you feel like selling early.
