Tether (USDT) has overtaken XRP to become the third largest cryptocurrency by market capitalization, as Ripple fails to gain adoption amongst retail investors.

As for Ripple (XRP), it's been a race to the bottom, its market cap has collapsed from a high around $130 billion in January 2018 to the current one under $9 billion. At one point XRP was jockeying for the number two position with Ether (ETH), however, currently, the combined market cap of XRP and USDT is still $5 billion behind Ether.

USDT trading volume dwarfs XRP’s

Perhaps part of the problem for XRP is a lack of traction with retail investors. In terms of daily trading volume, USDT dwarfs XRP. USDT’s average daily volume in May has outpaced XRP’s by a factor of 25.

But this doesn’t mean that the race for third place is over. With a decent bull run, XRP could blow past its stablecoin rival, which cannot move up or down by more than a few percentage points.
