Just scrolled through my Moments and saw the 2017 crypto trading scene on Yuanbao. Out of all the coins, only $BTC, $LTC, $DOGE, and $ZEC are still around—everything else has either been delisted or gone to zero. After one cycle, most altcoins end up as a mess, let alone now that we've gone through two cycles. To put it bluntly, 99.9999% of altcoins are destined to either go to zero or get delisted. Long-term, buying Bitcoin is your best bet!
