10. Receive BTC and use the app
Once you have received your satoshis, you can share them with friends or family while testing out all the advanced features of your non-custodial Bitcoin wallet; additionally, you can tap the wallet-shaped button below the Bitcoin price to access your portfolio, where you will see the value of your holdings fluctuate in line with the price of Bitcoin.
11. Investment Portfolio
Your investment portfolio provides a detailed view of your wallet's actual value by categorizing each address as a distinct asset or holding. You can track value fluctuations as the price of Bitcoin rises or falls; the system compares the price at the time of a specific BTC deposit against the current market price to show whether your portfolio is in profit or at a loss. However, since you own the actual Bitcoin units, no one can take them away from you the monetary value is merely speculative and fluctuates with the price. Unlike on an exchange, where you risk losing your funds, here your Bitcoins remain yours; even if the price were to drop to zero, you would still retain the units in your wallet.
12. Example of a price change
As you may have noticed in the previous image, the price of Bitcoin was $84,466.38 with an available balance of 0.01390528 BTC; multiplying that by the price yields a total value of $1,174.53, representing a gain of +$15.87. Now, if we compare this to the current Bitcoin price of $84,263.01 which updates every two minutes we see a drop in your gains because the price has fallen; your profit is now +$13.04, a decrease of about $2.83. However, the key takeaway is that your holdings remain intact 0.01390528 BTC and you can transfer them to anyone on the Bitcoin network. That is the major difference between a standard exchange and NidusCripto: we restore sovereignty to individuals, just as it was always meant to be. That, my friend, was the original purpose of Bitcoin: to achieve financial sovereignty.
