No, Ethereum isn't capable of doing what XRP does. Vitalik admits as much and is pointing at ETH 2.0 as the path to fix the many problems that ETH has.
Also, it's looking more and more every day like the SEC is going to move to call Ethereum a security. Gensler has stated that he agrees with Jay Clayton's assertion that any coin that had an ICO is a security. When he was recently asked specifically about Ether's status as a security under the Howey Test,
he refused to answer. Further, during the XRP/SEC trial, the SEC has distanced itself tom William Hinman's speech that gave ETH a pass on being a security, saying that was only his personal opinion. ETH is not out of the woods yet.
As for me, crypto is my favorite subject in the world right now, outside of my kids. I'm more than willing to bring clarity to questions or debate the issues around it. I think this is an important moment in time, and that people are going to get rich or get REKT depending on what their holdings are, and what happens with regulation. I think people should be less tribal and more analytical at this moment.
But I could see people criticizing me because I've consolidated all of my holdings into XRP. That could be considered tribal. What I will say is that my position is based on my own personal analysis of the market and the regulatory environment. I think XRP is the most technically sound crypto, which will pass the regulatory phase and become a safe haven crypto. Once this happens, and once Tether is regulated out of existence (and the subsequent market crash that I believe will come with that happens) I will be re-deploying into whatever cryptos are left standing.
