I haven't gotten into Ethereum, yet - but it's at the top of my list for cryptos. With companies like Toyota and Samsung also invested in it, there's no one, single country that can completely wreck it without there being some major pushback from global companies. These are big-time players. I think it's as safe or safer to invest in as BitCoin. Could it go bad? Sure. But, that can happen to anything. As long as you have a good amount of physical gold and/or silver, your risks are reduced, greatly.
Absolutely... diversification is paramount... but keeping in mind that if the platform itself cannot be easily targeted the large corporate users certainly can... Government will always try and get its share... cheers
