5000000 DOT
You can buy DOT here.
https://www.cryptopia.co.nz/Exchange/?market=DOT_BTCToday they are selling for 0.0000037 bitcoins each. Buying 5000000 at that price would cost 18.5 bitcoins, which is $248529 today.
However in early January DOT were selling for less than 100 sats each, so the 5000000 needed to list a coin would have cost less than five bitcoins.
