You lose nothing in a swap as there will be fewer coins. After the swap, the value of each coin will be worth more.
I don't think you can read properly, let me explain the swap in more detail:
1. There will be a 200:1 Coin Swap.
2. There will be a 3:1 Max Supply Swap (300 Billion becoming 100 Billion Max Supply).
3. For the swap to be fair, the Coin Swap should be 3:1, because 300 Billion Total Supply is becoming 100 Billion Max Supply.
4. The Coin Swap is not going to be 3:1 (300 billion cap becoming 100 billion cap), but it will be 200:1!
5. Technically, you will lose 98.5% of your coins after the swap, because the Supply cap is being reduced only 3:1, while your coins are getting reduced 200:1 instead of also 3:1.
If you can't understand English, then I'm sorry this is not the forum for you.
