"Bitcoin sucks by the way. It is slow, it can cost $20 to send some, people spam it and kill the network all the time. Even doge is better."

This was true a few months ago.
The latest Bitcoin Core 0.16.0 has segwit by default. Faster, and low fees.
I'm not sure how anyone is paying $20 fees now?! you must be doing something wrong. I regularly see payments worth over $10,000 and the fee is less than 50c. The days of high fees are over my friend.
