The current Bitcoin (BTC) price bull run seems almost unstoppable right now as BTC just notched another new high on Feb. 17.

The psychological barrier of $50,000 finally broke on Tuesday after multiple tests of this level in the previous week. In addition, banks are revealing their interest in BTC, and more public companies are starting to hop on the Bitcoin bandwagon, with the first German company revealing its position today.

This rally could now extend to $63,000. Meanwhile, altcoins are feeling some pain in their BTC pairs as a result while Bitcoin dominance is crawling back up. The primary questions are if Bitcoin can sustain this run and if altcoins will drop in their BTC pairs.

Bitcoin crushes further after holding critical levels

Bitcoin’s price has been grinding up in the past few weeks, establishing some potential areas of support in the event of a pullback.

After the breakout above $40,000, the $43,000–$43,500 area quickly became the new level of support as a launchpad for more upside.

The chart above shows this continuation is seen as BTC rallied toward the next point of interest. This area is found at the 1.618 Fibonacci level around $50,000. This key level is also an important psychological barrier. Bitcoin’s price has successfully cleared this resistance zone and is currently trying to climb higher.

Now, the critical area to watch is between $47,250 and $48,000. As long as that sustains support, Bitcoin’s price can continue running towards$54,000 to $55,500.

Key Fibonacci levels to watch for BTC price

The daily chart for Bitcoin shows the next points of interest if the rally continues. During such an upward grind in price discovery — as the current price of Bitcoin is 150% higher than the all-time high in 2017 — the Fibonacci extension tool is useful for determining the next key levels to watch.

The first 1.618 Fibonacci level has been reached, while the second is at the 2.618 Fibonacci level. If the price of Bitcoin continues moving up, a rally toward $63,000 to $66,000 is on the table as long as $47,000 to $47,750 holds, as previously mentioned.

Bitcoin dominance is recovering

The weekly Bitcoin dominance chart shows a clear breakdown since the peak high in December 2020. Historically, Bitcoin dominance tops out in December, after which altcoins rally in January and February.

This is exactly what happened in January and so far in February. However, after such a monster run, a correction in altcoins is very likely. The BTC pairs of those altcoins should now see a consolidation period for some potential support/resistance flips.

However, altcoins may see a pullback if BTC continues to climb. In other words, the altcoins' U.S. dollar values may stay the same, but they’ll go down in value against BTC. Traders and investors should be aware of this cryptocurrency market phenomenon. A heavy correction for altcoin-BTC pairs is very possible, especially if Bitcoin’s price runs to the next target at $63,000.

Crucial level to watch for Bitcoin

The four-hour chart for Bitcoin shows one critical level to watch. Once again, the region between $47,250 and $48,000 is a must-hold area for higher prices. If that level fails to sustain support, a significant correction is likely to happen, possibly to the next major support zone between $43,000 and $44,000.

For the bulls, $55,000 and possibly even $63,000 to $65,000 will be the next targets if BTC price continues its rally.
