Cryptocurrencies across the board have surged in the past 24 hours to see many reach new all-time highs.

The unprecedented rise, which will like fuel speculation of bubble-like behavior, saw Bitcoin $2,400, Ethereum breaks $200 and Litecoin challenge previous highs.

The top 10 cryptocurrencies all posted gains in the run-up to press time Wednesday according to data from Coinmarketcap.

Further down the charts, other huge movers came out, including a 54 percent rise for Stratis and 68 percent for the Lisk Foundation’s LSK token.

At the same time, it is becoming more and more difficult to determine the underlying cause for the continued market buoyancy in both Bitcoin and altcoins.

Talk of a final SegWit deal for Bitcoin may have fueled its rise, yet with details have yet to be ironed out, talk is turning to U-turns from certain members of a group originally plugged by Barry Silbert as agreeing to implement SegWit by September.

SegWit is the major preoccupation of the Bitcoin community on social media meanwhile, with price celebrations eschewed in favor of debate about the strength of Silbert’s plan and likely saboteurs.

Price-wise, even commentators such as Vinny Lingham have implied the next significant barrier will not be until Bitcoin is within striking distance of $5,000.
