It's a necessary evil that unfortunately affects true believers in blockchain products. Most altcoins are inherently tied/pegged to ETH or BTC, so as we flush out garbage/scam projects, so too will ETH and BTC suffer. It's the nature of the market. The larger question at hand, is how will the crypto space react post-cryto purge. Will altcoins rebound? Will new sub-par projects emerge (and people invest in them)? Ethereum and Bitcoin are 'too big to fail' at this point, and truly pose value-add solutions. At some point, believers and supporters will buy back in. Nothing you can do other than ride the wave, move your coins to tether (or some other stable coin), or panic and sell everything (not suggested).
