MicroStrategy's Bitcoin buying plan—once maligned by big businesses—has produced blockbuster profits for the software company amid the latest Bitcoin boom, pushing its stock price to all-time highs in recent months as its stash tops $40 billion worth of the coin.

And its success has inspired a crop of copycats, though MicroStrategy founder and Executive Chairman Michael Saylor probably doesn’t mind—he’s been advocating for such a movement for years now.

In recent months, several more publicly traded firms have greenlighted corporate strategies to stack Bitcoin as a treasury reserve asset, while others that have already invested in the cryptocurrency are building up their holdings of the asset.

More than 70 companies have dived headfirst into MicroStrategy's crypto-first business strategy at a time when Bitcoin is flying high: President-elect Donald Trump vowed last summer to create a national stockpile of the digital currency, and the token hit an all-time high of $108,000 in December.
