Cryptocurrency might sound complex but as time goes on it will be normalized just like the internet. Anything can become recognized as a currency, What makes these "coins" so special is their cryptography and server makeup.
Blockchain is the backbone of cryptocurrency. It's an immutable record keeping system with internal cryptography. Technology is generally very sparsed out and most large projects like credit and debit card processing have to outsource things like their security, encryption, or anti-virus capabilities.
Blockchain in most cases doesn't have a centralized server. Like bitcoin it's open source so anybody can participate. Instead of having a centralized server in one office building that uses a antivirus software for protection. Bitcoin uses the different placement of all it's server participants as it's encryption. Constantly verifying itself for accuracy using its outspread server to its advantage.
That's why bitcoin, ethereum, and the other major blockchain projects have never been hacked. The exchanges these currencies are traded on have been hacked, but never the cryptocurrency itself.
In theory if somebody controlled over 51% of a blockchains servers, they could hack the system and alter or delete records. However this would be incredibly difficult to do and would require more technical power than the world's best quantum supercomputers posses.
Now how does it make money? Well it's just like stocks! Or tulips, if you're familiar with the Dutch tulip bubble. Speculation and commerce will eventually drive the price of anything. Why many financial experts and now institutions are adopting cryptocurrency is rather simple. Blockchain.
Cryptocurrency isn't just a stock like asset. It's direct buying power is growing, El Salvador added bitcoin as legal tender and added it to their national reserves. Many other Latin countries are in talks of doing the same. Geothermal mines are beginning to open and bitcoin is already better on the environment than paper money/coins.
Ethereum is a blockchain project that can scale with most softwares and offers them exceptional blockchain services like security and high performance data management. The more softwares that adopt Ethereums platform, the larger Ethereums network size grows and with it - the projects value.
It's hard to imagine a future without cryptocurrencies. Many argue its just a fad. Many argue its here to stay. Regardless numbers don't lie, you can't deny its growth. You could have invested in gold or bitcoin 10 years ago or 1 year ago - both times bitcoin would have been the better investment. Paired with the amount of traditional finance that now utilizes bitcoin and blockchain technology. Business Goals Agency agrees with those saying crypto is here to stay!
