This is the problem I take with your stance. Use BTC only, if that's your preference. That's all good! However, when you're effectively telling others they shouldn't use altcoins because they're not Bitcoin, that's where the problem lies. I'm not telling YOU to stop using Bitcoin and I'm not insulting your choice.

If I think it's a shitcoin then I'm going to come out and say it's a shitcoin. It's not like I MUST say something positive about it.
If you still have a problem with that, then either do something about it or fuck off.
Little to do when you've successfully played the victim, the superior, the fool, and the smartest person in the room all at the same time. Bravo
