For the love of god, send a dummy transaction before sending your whole stack.

Title.

I have seen so many posts about people mistyping addresses and losing their crypto recently. I am posting this again before some dude inevitably does the same thing again.

Paying fees twice is worth the peace of mind. If you're sending a small amount and it's a crypto with high fees (BTC, ETH), I'd either leave it on an exchange if it's there, wait until ETH 2.0 if it's ETH, or just send away if its so small that you won't get bummed out if you lost it.

Anything else and there should be absolutely no excuse for you not to send a dummy transaction.
