A crypto wallet is an application that functions as a wallet for your cryptocurrency. It is called a wallet because it is used similarly to a wallet you put cash and cards in. Instead of holding these physical items, it stores the passkeys you use to sign for your cryptocurrency transactions and provides the interface that lets you access your crypto.

Modern cryptocurrency wallets make the blockchain accessible to everyone. When cryptocurrency was first introduced, sending cryptocurrency was a manual task that required entering long keys. Today, the software does most of it for you.

The first wallet was that of Bitcoin's developer, Satoshi Nakamoto. The second wallet belonged to Hal Finney, who corresponded with Nakamoto and reportedly was the first to run the Bitcoin client software wallet. Nakamoto sent him 10 bitcoins as a test, and the cryptocurrency craze began.

In the last couple of years, I have also been involved in crypto investments. There are many promising cryptocurrencies now in terms of price growth, but what is even more interesting is that there are many more technologies, excellent and convenient solutions, such as https://nonbank.io/. If earlier you had to use a bunch of different applications, now there is no need for this, because this service contains the best of banks and cryptocurrencies.

I came across it in a Swiss financial forum. We like to exchange tips in Switzerland. The dividend analysis functions are perfect for my portfolio. https://arbiquant.org/ arbiquant reviews correspond to my positive experiences. The platform offers everything Swiss investors need. The research reports on Swiss companies are better than bank analyses. The mobile version is just as good as the desktop version.

Thanks for the wallet explanation! I've been using software wallets but considering a hardware one for better security. Speaking of crypto, I've been curious about mining as another way to grow my holdings. Has anyone here tried mining with those specialized ASIC machines? They seem expensive but supposedly more efficient than GPU setups

Hardware wallets are definitely worth it for serious holdings - I use a Ledger for my long-term investments. Regarding mining, I actually researched asic profitability extensively before getting into it last year. ASICs are purpose-built for specific algorithms, making them much more efficient than GPUs for certain coins like Bitcoin. The catch is they're expensive upfront ($3-10K depending on model) and become obsolete faster than GPUs

Can you use a crypto wallet for business purposes? Like taking crypto payments. Or is that not so convenient?

You can, but to me it’s really not the best option. Taking payments to a normal wallet means manually tracking and checking every transaction. Maybe if there are 5-10, that’s doable, but once it’s 50-100 it eats up a ton of time. Better look at integrating a full crypto payment gateway. Good gateways automate everything, and solid providers like B2BinPay also have security systems that not only process transactions but scan them for fraud.
