@patrick_mrozowski how much of the invested sums is eaten up by fees? Especially if you go through Coinbase... don't they have a minimum fee?
Patrick MrozowskiMakerPro@patrick_mrozowski · Founder, Crumbs
@sliver86 We use GDAX which is the exchange owned by Coinbase and Crumbs covers the fees for your investments regardless of the amount!

@sliver86 @patrick_mrozowski Do I need to open an account on GDAX? Tried the app and don't really get it.
Patrick MrozowskiMakerPro@patrick_mrozowski · Founder, Crumbs
@spike_spieg No you don’t. Every time you make a purchase with the connected debit or credit card you will see your rounds ups appear in your portfolio. When your ready to cash out you can choose which crypto wallet you want to take from and that amount will be sent into your bank account.
Spike Spieg@spike_spieg
@patrick_mrozowski Thanks for the reply. So you process the payment and hold our cryptocurrency, not GDAX. Right?
Patrick MrozowskiMakerPro@patrick_mrozowski · Founder, Crumbs
@spike_spieg So the users crypto is stored in Gdax, they use a cold storage offline system so it’s very secure.

@aminbenselim @patrick_mrozowski I think at the very least a web version would be nice, I don't own any Apple products but have been looking for a product like this for a while

@patrick_mrozowski Great idea, similar to acorn and micro-investments apps but for cryptos - I can see this app becoming Unicorn HUGE if the following things are done fast. Would love to talk to you more about it :) See few ideas below: 1) Offer free or minimal trade fees (like how Robinhood captured the market by offering free stock trades) 2) Add both a manual, automatic and AI (eventually) trigger functionality so that those who have buy and sell criteria can decide investment strategy and execution. 3) Ability to buy or sell instantly (coinbase's instant, no waiting couple hours - unless the crypto servers themselves fail) and lots more. Would love to talk about this more!

TLDR Crumbs pays for all fees, at a 1.99$/month subscription. If you pay out your Bitcoin only once a year, the network fee Crumbs pays is higher than the annual subscription income. What‘s more, funds are stored in Crumb‘s GDAX account. Who guarantees me that Crumbs does not walk away with my Bitcoin if the business goes bust? Sorry, but this looks a bit sketchy.

@josef_moser Hi we keep a reserve to ensure we always have enough USD to cover all users investments in case of any unfortunate circumstance. Your balance is withdrawn from a USD reserve and sent into the users connected bank account.
