but then we get into other questions such as "what is an acceptable level of bias in an experiment where you perform it some number of times, be that 1000, or more?"
When considering generating private keys for bitcoin, then my answer is zero. I don't see why you would settle for anything less. This is why I advocate for using coin flips with von Neumann's algorithm, since by doing this you can be certain you have eliminated any bias in your coin, as well as not introduced any new bias by performing randomness extraction or other processes you don't fully understand on your data.
yeah now that you put it that way, i guess it does make sense. why settle for less? i looked into shuffling a card deck to generate entropy once but i'm not sure if that is as safe as this von neumann method. but i dont see how shuffling a card deck could be biased as long as you shuffle it enough times.
also it's alot faster than flipping coins.

Any method of testing for bias can never rule out bias 100%, only make it less and less likely but after an exponential number of test flips/rolls.
that's why it's hard to test something and people forego that, at their own peril of course  Cheesy

People involved in bitcoin who have the ability to read and analyze code, as well as the time and motivation to do so for free, generally aren't using random low quality wallets like Cake which they stumble across on the app store, which might explain why nobody picked it up sooner.

I mean they got a pretty large user base from what it looks like. 100k+ downloads off google play is not such small potatoes. Not every random low quality bitcoin wallet has XMR/BTC/LTC swapping going on either. Surely alot of people that used Monero used it for that exact reason...

Cake Wallet allows you to safely store, exchange, and spend your Monero, Bitcoin, Litecoin, and Haven. Cake Wallet is focused on an excellent transaction experience.
