I Finally Screwed up with Bitcoin

I'm not sure if I can recover my funds sent from Nano S Ledger to Poloniex, but I finally screwed up. I think I tried sending bitcoin to a bitcoin cash address. I've made quite a few transactions and I've had a perfect record. It's amazing how easy it is to make a mistake in the crypto world. Maybe that's why I'm the only one I know personally who trades in cryptos.

Have you made a similar mistake in your trading adventure in the crypto world? I'd like to know what you have done to make yourself feel silly like me.
