Meanwhile, the U.S. Securities and Exchange Commission recently delayed deadlines for bitcoin spot ETF applications.
We dive into what’s going on with the bitcoin spot ETFs in the U.S., why it matters and the odds of the SEC approving one in the near future. We also talk about Europe’s first bitcoin spot ETF, how these investment vehicles in general could impact crypto exchanges’ trading volumes and what else is in store for them.
Customer Reviews
So good now
I’ve been a listener from the start and the conversations and production quality has only ever improved. Jacquelyn is such a researched host and has provided a lot of clarity for me in the current state of the industry. I’m always most intrigued by episodes with guests I haven’t heard of especially because it feels like an insider’s perspective on an already niche market where you need to know to ‘know.’ Chain Reaction breaks that down and keeps my finger on the pulse. Big recommend
Has become a fave!
Jacquie has a way of asking every question I want to know. This podcasts definitely isn’t just for people obsessed with crypto and web3. It’s a great way to dip your toe in if you’re crypto-curious as they say!
Awesome!
Excellent first episode! Looking forward to many more. Keep it up!
