Bollcoin, October 23: Bankless founder David Hoffman said in a post that a group of tokens he calls "2017-era Bitcoin clone coins" have recently gained traction again. Among them, PRL rose 30% this week, with a fully diluted valuation (FDV) of about $4.2 billion; QTC rose 300% this month, with a valuation of about $1.8 billion based on a total supply of 21 million tokens. Hoffman also noted that it is worth watching that such tokens, which adopt a fixed supply cap of 21 million, are commanding billion-dollar-level valuations.
