The problem, though, is that using Monero friendly services I’ve tried both buying Monero directly and buying something like Ethereum or Litecoin for converting to Monero. I’ve used multiple apps and have experienced problems with each, as described in the original post. And the “cold storage” wallet I would like to use doesn’t support XMR as of yet.
While I would certainly love to fully migrate to XMR when I have a firmer grasp on the whole crypto concept, I’m not particularly concerned with private payments at the moment.
I just want to know about MobileCoin usability per the Signal app.
