If you've been an investor for long enough, you've made at least one mistake that caused you to lose a chunk of cash. For me, that was making one of the most basic crypto mistakes you can make. I sent all of my crypto from one wallet to another without making sure if it was the correct wallet or not. So I lost a large chunk of money, and with it, a large chunk of my interest in crypto. 

The worst part about my mistake was that I had already had been in crypto for years at this point. I had been making transfers quite often using this wallet and the wallet I was supposed to be sending my crypto to. This was on the Algorand blockchain after all, and transfers are cheap on that blockchain. So transferring Algos around was almost a daily thing. 

The cause of the bad transfer was a silly thing called panic. Not panic because crypto was falling, I'd experienced that a lot already by this point. No, the reason why I wanted to transfer was because of a hack of several Algorand wallets that was happening. I was nervous that the hacker wouldn't stop with the wallets from MyAlgoWallet and would eventually hack Pera Wallet and Defly.

So I panicked and sent my coins to Coinbase to swap for another cryptocurrency. The address looked different but at the time, I was tired and panicked so I sent the coins anyways. After about a minute, I started to get worried. That's when I looked again at what my crypto address was on Coinbase and realized that it wasn't the address I sent my coins to. I had lost all of my Algorand.

So I didn't get hacked and lose all of my Algorand that way. No, I panicked and lost my coins on my own in a very dumb way. But it was a learning experience. Don't make decisions when you are not rational. Because if you make a decision when you are not rational, it will become a mistake. And potentially it will be a very big mistake.
