Bitcoin is structured as a sequential chain that adds blocks at frequent intervals. IOTA, on the other hand, has Tangle, which uses Directed Acyclic Graph (DAG). With this, it's easier to get high transaction output with no transaction fees. As the technology continues to grow and more people make transactions, then the system becomes faster and more secure than Blockchain. It's almost as if it's a self-sustaining organism.
When you pay transaction fees with Bitcoin's Blockchain, most people don't know where that money goes. With IOTA, you know exactly where it goes. Another key feature of Tangle is that it uses transaction fees to cover the cost of spam attacks and mining. Furthermore, the network has a limit for the minimum amount of a payment. Hence, anything below that limit makes money transfers unsuitable.
No one likes limits. You might think you do, but you don't. Hence, you'll love this new network because it has zero limits in its scalability. Furthermore, Tangle doesn't require any advanced hardware because it doesn't even use scripts with complex processing logic. It's just clean and simple. Lastly, Tangle allows plenty of room for growth. Unlimited room, in fact, and this is all without increasing the balance information in storage. As a result, this technology is more efficient than most. Keep an eye on how it evolves. It just might put Bitcoin out of business.
