 ranged below a critical weekly close target on Friday as analysis warned its multi-week uptrend was in danger. 

BTC price lags $1,500 below crucial level

Data from Cointelegraph Markets Pro and TradingView showed BTC/USD trading at around $46,000 Friday after rejecting near $47,450 the day before.

That level marks the lower bound of Bitcoin’s uptrend on the weekly chart, one that has continued since mid-July.

Now, BTC/USD needs to reclaim it, trader and analyst Rekt Capital said, in order to preserve that trend.

With Bitcoin closer to $1,500 below the higher low target at the time of writing, much work was left to do over the weekend to secure a more bullish close by the end of Sunday.

Tezos outshines the rest

After standard moves in line with the majority of major altcoins, XTZ/USD suddenly began to break out, gaining 24% on the day to become the best-performing cryptocurrency. The pair hit $6.53, its highest since mid-May.

The events coincide with increasing nonfungible token interest on Tezos courtesy of music star Doja Cat, and its blockchain handled 400,000 daily transactions for the first time this week. 

Meanwhile, the largest altcoin, Ether

“Expecting new highs,” he forecast after ETH/BTC reversed upward at 0.071.
