Inside Bitcoins unsustainable matters
When they first came out, digital currencies (DCs) have represented the element of novelty in the worldwide trend of digitalisation. The high potential to turn payments from physical to digital that they represented at the beginning was incredible. The most recent developments, upon whom the deregulation trend of the market was surely the riskiest, jeopardised such high potential, turning cryptocurrencies into a speculative asset. Reasons to this can be traced from DCs market volatility towards their energy-intensity. We are exploring the main drawbacks  of Bitcoins because they show meaningfulness with regards to the overall Digital Currencies ecosystem.
Factor number one is volatility. Data provided by Statista  show how instability tampers with every possibility investors have to face Bitcoins’ fluctuations. Few comments could be made except from the fact that, in a time span of only four months (October 2020 – February 2021) , BTC price in USD has been roughly sextuplicating. Nonetheless, BTC tipping point has been already overpassed and a sustained decrease is already on its way. If we look further at the pricing , this factor cannot be denied. Nor could risk be underestimated  since bookmakers convene that average market risk in Bitcoin  is “9.5 times higher than that of USD/EUR and 2.9 times the SP-500 risk”. Overall, volatility is the most unravelling factor characterising the world of unregulated Digital Currencies – economists  say.
The second, factual reason, of DCs scepticism stands in their scarcity. On the one hand, in an institutional exit, Christine Lagarde (the former International Monetary Fund Chief and current European Central Bank President) considered data as the new gold  - and Digital currencies as the new Gold standard  by extension. On the other hand, Digital Currencies face a problem Fiat Money does not have: a limited offering . BTCs are supplied by a digital technology which sparks much more controversies than the benefits it could have entailed. In other words, Bitcoins are not sustainable . Their issuance process is energy-intensive  and shifts the matter from volatility to carbon footprinting.
Putting the pieces of the puzzle together, BTC supply scarcity relies on the mining capacity that could concoct other BTCs. Such capacity is proved to be extremely limited by the huge amount of energy that a single BTC needs to be “mined”  (see the figure above). This second factor is endorsed by academics  and observers  alltogether. This explains why the curve representing the number of circulating BTCs is lowering and precisely, its position is resting in a sort of plateau  (read below).
Conclusions take us to say that Bitcoins future is jeopardised by their own volatility, their in-made scarcity and the energy costs their usage and mining entails. As long as one of these will not be properly addressed, sceptical observers will continue to move their own critiques  to Digital Currencies in general and Bitcoins in particular.
