you may buy and sell ETH, but you can never leave Ethereum even its most prolific haters will be forced to use it in the coming years, as almost every entity they interact with comes to adopt THE CHAIN in some manner Ethereum is not a mere "number go up" technology. it is a DEEP ecosystem which will completely redefine "trust" at a civilizational level. indeed our entire civilization is built upon trusted intermediaries- many of whom have a track record of failing us. and Ethereum can be a big part of the solution and that is why you see so many ultra-high conviction ETH whales stick around, cycle after cycle, even though they could retire 10x or 100x or 1000x over, while other coin communities sell and move on to these participants, the job's not done until it's ALL onchain and if you don't understand, i don't have time to explain it to you (today), but i will endeavor to do so in the coming months as it's important that you understand it
