I’ve been actively involved in the cryptocurrency space for about five years now, and I’m always on the lookout for efficient and reliable exchanges. Recently, I decided to really put ff.io, also known as FixedFloat, through its paces. I’d heard whispers about its speed and non-custodial nature, and I wanted to see if it lived up to the hype. This isn’t just a regurgitation of what I read online; this is based on my personal experience over the last six months.

What is FixedFloat and Why Did I Choose It?
For those unfamiliar, FixedFloat is a non-custodial crypto exchange. This is a huge deal for me. What it means is that I never relinquish control of my coins to the platform. I initiate the trade, and the exchange facilitates it directly between my wallets. I was initially drawn to it because I was tired of exchanges requiring me to deposit funds into their wallets, creating a potential security risk. I’ve had a bad experience in the past with an exchange being hacked, and I’m very cautious now.
My First Impressions & Initial Trades
The interface is… minimalist. It’s not going to win any design awards, but honestly, I appreciate that. I found it very straightforward to use. I started with small trades – swapping Bitcoin for Litecoin, then Litecoin for Dogecoin. I did this intentionally to test the speed and fees. I was genuinely impressed. The transactions were completed remarkably quickly, often within minutes, even during peak network congestion. I compared the rates to other popular exchanges like Binance and Coinbase Pro, and FixedFloat consistently offered competitive, and sometimes even better, rates. I noticed they heavily promote their Lightning Network support, and I did utilize that for a few smaller transactions, which were almost instantaneous.
The Good: Speed, Security, and Anonymity
- Speed: As I mentioned, the speed is a major selling point. I’ve rarely experienced delays.
- Security: Being non-custodial is a massive win; I maintain full control of my private keys.
- Anonymity: While not completely anonymous (KYC may be required for larger transactions, as with most exchanges), the platform doesn’t require extensive personal information for smaller trades.
- Fees: The fees are transparent and generally lower than many centralized exchanges.
- Lightning Network Support: This is fantastic for quick and cheap Bitcoin transactions.
The Not-So-Good: Potential for Order Suspension & Customer Support
Now, it’s not all sunshine and roses. I did encounter one situation where an order was temporarily suspended. I was attempting a larger trade of Ethereum, and FixedFloat flagged it for review. I received an email requesting proof of funds, which I provided, and the order was processed within a few hours. While understandable from a security perspective (they state they reserve the right to do this to prevent suspicious activity), it was a bit inconvenient. I also found the customer support to be… slow to respond. I sent a query about the order suspension, and it took almost 24 hours to receive a reply. It wasn’t unhelpful, but the response time could definitely be improved. I’ve read other reviews online echoing this sentiment.
My Experience with a “Mistake” Transaction
I’m usually very careful, but I did accidentally send Bitcoin to the wrong address once (not on ff.io itself, but a wallet address I copied incorrectly). I contacted FixedFloat support hoping they might have some insight or be able to offer assistance, even though it wasn’t their fault. While they couldn’t recover the funds (which I didn’t expect), they were very sympathetic and provided helpful resources about dealing with lost crypto and avoiding scams. This showed me they genuinely care about their users, even in situations outside their direct responsibility.
Scam Awareness: A Word of Caution
I’ve noticed a lot of warnings online about scammers targeting users of platforms like ff.io. I’ve personally received a few private messages on other platforms offering “help” with recovering lost funds or promising to “hack” wallets. These are always scams. FixedFloat themselves have warnings on their site about this, and I strongly advise everyone to be extremely cautious and never share your private keys or seed phrases with anyone.
Overall Verdict: 4/5 Stars
Despite the occasional order suspension and slow customer support, I’m very happy with ff.io. The speed, security, and competitive rates make it my go-to exchange for most of my crypto swaps. The non-custodial nature is a huge plus, and I feel much more comfortable using it than centralized exchanges. I would recommend it to anyone looking for a fast, secure, and reliable way to exchange cryptocurrencies, but be aware of the potential for order reviews and the importance of being vigilant against scams. I, Amelia Harding, will continue to use this platform for my crypto needs.
