Once people who have money in Etherium are awfully rich, Monero might be getting some investments from there also and it might mean a mega move in the price of XMR.
Therefore it is good not to start a war against ETH but start to tell them about a great opportunity to diversify their assets. ETH serves its purpose well and XMR has entirely different purpose (it's intended to be cash equivalent money).
If Ethereum is vaporware, I'm going to say so. This whole "don't alienate the potential investor" is the same thing the dashtards used in an attempt mitigate criticism. I'm still not convinced if Ethereum will or won't do what it claims--and frankly, I don't really follow it as it isn't in the privacy sector--but if it looks like BS, I'm certainly going to say so no matter what the implications are to anyone's stack. Grow a spine, TC.
Regardless of whether one alienates ETH investors or not it is certainly the case that ETH has brought a lot of money (and margin buying power) into the market and I do agree with TC that some of that money is spilling over to other markets (including XMR but also unfortunately including a new crop of pure scamcoin that are being launched at an increased rate).
