If he increased his BCH holdings in March 2018 it wasn't his best move for sure. It was rather a "this will get you bankrupt" move.
For every 800 USD spent then he has 300 now. He's in a worse situation than if he bought BTC in the peak of 2017 bull market. There's not much to brag about if he was ever planning to. I don't see BCH winning any wars against BTC now or ever.
August 1, 2017 when they plan to create BCH to stop bitcoin from rapid increasing I think but the coin market of BCH has a expensive coin market cap and I also don't think that it would success if it overtake bitcoin. For now, the BCH still dump and dump until no one who want to buy it because of the price now.
