Crumbs is a micro investing app that rounds up the spare change from your everyday debit and credit purchases and invests it into a basket of cryptocurrencies. Investing in cryptocurrencies has never been easier or more convenient.


Once your bank account has been linked, you select a portfolio that accurately reflects your investment strategy. Whether you want to keep your investments moderate or you prefer a more aggressive approach, Crumbs has a portfolio for you. If you’d like more control over which cryptocurrencies you invest in, you can create your own basket. From there, Crumbs will calculate your spare change made on purchases and once that amount equals $5.00, your spare change will be invested into the selected portfolio. Just sit back and watch your spare change turn into crypto. You can sell your crypto anytime and directly deposit funds into your bank account.


Round Ups -- Passively purchase Bitcoin, Ethereum, Litecoin, Ripple, and other cryptocurrencies with your spare change from daily purchases.

Recurring Buys -- Set a weekly or monthly recurring investment to maximize your portfolio.

Buy/Sell -- Invest in any supported cryptocurrency at any time.

Multiplier -- Grow your Round Ups quicker by setting a multiplier of up to 5x.

Discover -- Stay on top of the market with access to live price charts and the latest in cryptocurrency news.

Great so far

I’ve only been using this app for several days but I like just about everything so far. It’s very similar to Acorns investing app except your investing your spare change into crypto instead of stocks. Plenty of coins to choose from already and I’m sure more are coming. My only issue so far is that when you create your own portfolio the lowest you can invest in one coin is 15%, while in the premade portfolios some coins are set at 1-5%. This isn’t even close to being a deal breaker for me, I’d just like the option to spread my money around a little differently than the options given. Other than that great job!

Developer Response ,

We are working on adding smaller allocations per crypto.

Thank you for the kind words :)

Offers Something Unique and Little Known

I have been using the app for a few weeks now and it has been a great experience. I just updated it and it has AN INSTANT BUY FEATURE (fiat to crypto). That really surprised me because there are a very limited amount of ways to currently to buy crypto with dollars... Crumbs has the cheapest fees and the least amount of steps too.

The app developer is very responsive and takes suggestions with an open mind. This is part of the Metal ecosystem and I also have their Metal Pay app too. Definitely a 5 star rating from me.

Incredible app that helps you accumulate crypto assets

I’ve been using Crumbs for a few months now (I got on the beta), and it’s amazing. You connect your credit/debit cards, and the app automatically rounds up your purchases to the nearest dollar and takes that money and invests it in a diversified portfolio of crypto assets (i.e. Bitcoin, Ethereum, Litecoin, etc). You can customize your own portfolios as well, add recurring roundups, get tailored news, and more. Highly recommend for both amateur and expert cryptocurrency enthusiasts!
