Thank you for your reply.
Who minted the first 130 million tokens and exchanges them against Leocoin ?
The Leocoin Foundation ?
As you can see on CoinMarketCap, there are about 129,367,839 LEOcoin² issued on the current X11 blockchain. In order to 'swap' them, we accordingly need around 130m of LEOcoin³ tokens on the Ethereum chain, so all users can swap. For that they can make use of exchanges - who swap the old coins for the new tokens - or do it themselve at the LEOcoin upgrade website, that you can find here:
https://upgrade2erc20.leocoin.org/.
I find your description of fairly normal upgrade/swap preparation highly peculiar, as if there would be something fishy. Yet when you are about to change 130million for 130 million, you need these available on both blockchains, right?
