$BTC Bitcoin is showing a faster rebound than traditional financial assets.

A cycle of trust in the bitcoin and cryptocurrency market is taking shape.

Bitcoin (BTC) is usually measured in dollars. This is how it is found in charts, in quotes, in analysts' predictions, and in the news. But nothing says it has to be this way. After all, the dollar is just another unit of measure: a monetary reference that the world chose or accepted due to hegemony, not necessarily due to virtue.

However, bitcoin can be compared against any other asset or unit of value. Against gold, for example, with which it is often measured in cycles of refuge or speculation. Against oil, if you want to evaluate its relationship with energy. Against the Argentine peso, if you seek a more dramatic perspective. Or against stock shares, like the Nasdaq or the S&P500, if what interests you is comparing it with the average performance of the traditional financial market.

And that is precisely what has just marked a new milestone: on this May 9, bitcoin reached its highest point in history when compared to the S&P500 (SPX), one of the most relevant stock indices in the world.

In the following chart, the BTC/SPY ratio is observed. Note that SPY is the BlackRock ETF that tracks the S&P500 index, and it currently costs 565 dollars per share.
