Crypto & investing
In this space the product isn't an app — it's trust that your money will stay yours and come back out the moment you ask for it. Every failure reads not as a bug but as intent, because people's savings are at stake.
Three findings
Trust vault: money exits as easily as it enters
The defining pain of this space is asymmetric flow: deposits are instant, withdrawals are blocked. Holds, frozen accounts, KYC loops, and "security triggers" turn a platform into a trap at the exact moment funds are needed. The winner makes withdrawal reversibility and predictability the core promise — not a footnote in fine print.
Money flows in without friction — getting it out is a different story14
Deposits are instant; withdrawals run into holds, "pending" states, manual review, or flat-out refusal. Users feel their funds have been taken hostage at the exact moment they need them most.
will not let me withdraw my funds and close my accounts I started
They will hold your money hostage. Tried to take money out of Robinhood and return it to the same account I had deposited the funds from
they let you deposit as much as you want but God forbid the time that you want to transfer funds to out of this app in that case they will call you scams
The login loop: code, verification, redirect — back to the login screen12
The authentication flow itself is broken: codes arrive late and expire, email verification loops endlessly, the PIN screen hangs. Users can't even reach their own funds.
the app and the website keep aaki g to sign and , reroute to confirm email and repeats this without log in success
sending me a code to recognize me but the time is not enough and everytime I go back to the site it comes back to start so when I get back to punch the code the time elapsed
Can't login. Typing my correct pin code, but it redirects back to login with pin. still same issue 3y later...
Account locked — and the only way to get help is through the locked account11
A perfect catch-22: resolving the access problem requires logging in, but logging in is exactly what you can't do. Support is only reachable from inside the app you're locked out of.
There is no way to contact support unless I am in the app. Bottom line is my money is trapped in the app that I cannot login to
I forgot my login and there is no way to contact customer support unless you're logged in
If you have issues with app you get absolutely no help! I believe I was hacked and now locked out of app and you have to have access to app to get help
KYC verification drags on for weeks and holds funds already inside9
Identity checks promised in a day stretch to a week, demand a video of you holding your ID, and fail without explanation. Most painful: re-verification triggered on an already-verified account, after which access to funds simply disappears.
Takes 2 to 3 months to verify you to your account. Once verified it still won't send because it senses a scam
my assets are held hostage until I upload quoted below : Video of you holding your ID along with you stating the following in the video
all of a sudden asked for verification again even after I had been verified and was using and then couldn't do anything no explanation as to why
Self-custody means coins silently disappearing by morning8
In non-custodial wallets, coins "vanish overnight" or land at an address the owner never authorized — with no one to explain it. The category's core promise — full control over your own assets — breaks down precisely where that promise is the entire point.
I had about 890 in usdc, next morning its gone like it never existed
all my coins were gone it said they were sent to some address an I didn't authorize anything mind you you also have to use a thumb print to get on my account so there security is trash
The balance was visible for only three days; suddenly, the funds disappeared, and the balance showed as zero. When I contacted support, they merely offered excuses
Change your phone or move countries — lose access to your own money8
Tying an account to an old number, device, or geolocation becomes a trap the moment anything in life changes. You can't update the phone number without logging in, and you can't log in without the old number — funds stay behind a wall.
unable to recover my account because it texts an old number I do not have. can't use any recovering feature on the app because nothing works
Until I changed my phone number and couldn't update it on Kraken. The support is lying about it
just shut down my account with funds on it for trying to change my phone number and support doesn't respond

Ideas users ask for themselves — each backed by proven demand.
Each idea: the market gap, exactly what to build, the core features and how to monetize — backed by review quotes.
9 apps
The leaders — Coinbase, Binance, Crypto.com, Kraken, Robinhood — invest heavily in features, new coins, and gamification, yet fail at three basic promises: let me withdraw, connect me to a human, and tell me why I'm blocked. Self-custody wallets (MetaMask, Trust Wallet) are surrendering their core value proposition — simplicity and control — by bloating into corporate super-apps where coins disappear overnight. Nobody is winning on the axis of calm versus anxiety.
