Fancy a break, mate? Amid the latest optimistic headlines on the trade front, cryptocurrencies are starting to come up again after a bit of a setback in the middle of last week. Over the weekend, we've seen a resurgence in Ethereum in particular as it wipes out the losses from Wednesday amid a drop towards $3,600.As price now moves back up to its highest since December last year, the question once again is will we see a potential break of $4,000? That has been arguably the biggest level in stopping the price action breakout for Ethereum for the longest of time.It was only one previously that we ever really saw a clean break for Ethereum above the key level and that was back in late 2021. That didn't last though, with the peak coming just above $4,800 before falling back. In similar vein, Bitcoin also broke to fresh record highs above $60,000 at the time before falling back to under $20,000 in the following summer. How the times have changed, eh?Throughout last year, Ethereum failed to firmly break the $4,000 level. So, this will be one of its biggest tests yet. If buyers can seek a break here, the sky's the limit. Otherwise, another rejection might just mark the high we'll be seeing for the rest of the year.But so far, the summer of crypto and the summer of collectibles continue to run hot across the globe.
