Cryptocurrency Price Analysis - week 19 and YTD (2021)

Cryptocurrency Analysis – week 19 and YTD, 2021

Markets and Elon are volatile  

Bitcoin and many other crypto projects ended the week sharply lower following a series of tweets from Elon Musk.

In February this year Tesla announced that it would accept Bitcoin as payment. On 13-May Musk posted on twitter a statement indicating that Tesla would no longer be accepting BTC for car payments due to its energy use, particularly its use of fossil fuels. Some were concerned over the amount of due-diligence Tesla had done on its original BTC decision given that the reversal took place just a few months later.

Arguments between Musk and BTC supporters continued where Musk indicated that the company may indeed sell their remaining BTC holdings and that due to the responses on twitter he may now go ‘all-in’ on Doge. The price action from Musk’s tweets and debate on BTC’s energy usage has now become the main focus in the space.

The ABC cited a report from the Cambridge University’s Cambridge Centre for Alternative Finance that showed 61% of BTC mining last year was powered by fossil fuels, with the remaining 39% powered by renewables, mainly hydroelectric energy.

Musk has long championed Dogecoin and has called himself the ‘Dogefather’. However, once his tweets regarding Bitcoin came out, questions arose about his support for Doge as it, like BTC, also uses a Proof-of-Work model to ensure its security. Musk responded that he still supports Doge and is working with developers to make improvements.

Other highlights:

  • Square confirms its BTC strategy hasn’t changed: Square’s CFO told Financial News that they have no plans to make further BTC purchases, but they are now revaluating where they are from a treasury standpoint.
