“More important than Square (NYSE:SQ) investing $50M in Bitcoin (BTC-USD) is sharing how we did it (so others can do the same),” tweets @jack.

He provides a link to a Square whitepaper describing how the company was able to purchase $50M worth of Bitcoin in a day without disrupting the market. The paper also details the security measures the company has taken to protect its crypto assets.

Even more important, says Dorsey, is Square’s investing in open source development with Square Crypto, opening access to patents in conjunction with Crypto Open Patent Alliance (COPA), and making Bitcoin more accessible and useful to millions with the Cash App.

Bitcoin is continuing with modest gains following this morning’s announcement of the big Square purchase. It’s up 2.5% to $10,934. Square’s ahead 2.7%.

The Grayscale Bitcoin Trust (GBTC) is up 8.8%.
