Not sure about this one.
1.5 BTC invested in the NXT IPO in Nov 2013 would have made you a millionaire today.
Really? How much NXT would that have bought you, and how much exactly would it be worth today? Are you talking about investing around $1500, since BTC was around $1,000 back then?
I haven't done the maths to get the 1.5 BTC figure but someone else in the forum said the exact same thing so I assumed it was correct.
I'll do the calculations just to make sure it's right:
The longest phase of the NXT IPO lasted 61 days - everyone could buy 1 NXT for 2 satoshis between September 28 and November 18, 2013.
1.5 BTC is equal to 150 million satoshis. This amount would have bought you 75 million NXT.
1 NXT is worth about 6 cents today according to Coinmarketcap.com so 75 million NXT would be worth about 4.5 million dollars today. Percentage-wise, you would own slightly less than 10 percent of all the NXT in the world.
