if you want to make impact with your podcast in the world outside of the crypto crowd, I highly recommend that you use libsyn as your host. I have used them for the past 3 years and find their service great. The plans start for as little as $ 5 per month and it will put you into all the major outlets - including spotify. They also are pioneering to get into pandora - so far, it is just a few accounts but might be open to all soon.
