A rapid-fire string of good news over the past week has help nudge up the price of Bitcoin.

A week ago the Bitcoin price was hovering around $225, which is somewhat disappointing since just six weeks earlier it was threatening to break through the $300 level.

But then we started to get some major positive Bitcoin news. Over the past few days, the Bitcoin price is up about 7%, trading in the neighborhood of $240.

The price of Bitcoin hit a 15-month low of $177 in January and has been fighting to rebound ever since.

The biggest jump came last Thursday, when news broke that Goldman Sachs Group Inc. (NYSE: GS) had joined a $50 million venture capital investment in Bitcoin payments startup Circle Internet Financial.

It was the largest and most direct vote of confidence for Bitcoin from Wall Street yet.

For about a year now, Wall Street has been sniffing around Bitcoin. The Big Banks see Bitcoin as a potential threat, but at the same time realize that they could exploit this new “fintech” for their own gain.

Regardless of the motives, Wall Street’s stamp of approval will grease the wheels of mainstream adoption of the digital currency. That’s why the news had an immediate impact on the price of Bitcoin.

Along with the Goldman announcement, several other pieces of positive news also buttressed the price of Bitcoin.
