That would be good. But how to define this good new altcoin? Since 2018, the vast majority of altcoins have depreciated greatly, regardless of how good they are at first glance. Looking at how the altcoin market is changing, faith in everything except BTC and ethereum is lost.
We still have EOS, BNB, XRP, and many more that is potential for growth. It is not only ETH that is developed but many cryptocurrency developers are trying their hard to deliver their promised road map. So don't lose hope yet for these altcoin but rather throw away any shitcoins that you are holding in your stash that is created for the sole purpose of money grab and nothing more.
