Byteball's 24h trading volume is very low, about 0.5% of it's market cap. For many other coins that's about 10 times bigger. I too think the lack of exchanges is holding back Byteball's adoption.
It'd really help to hop onto Binance - they seem to have the largest volume this past weeks. Sadly - we ourselves cannot list it. We need Tony to apply himself.
