Cryptocurrencies and Future of Money

Based on the needs of the economy and the society, money has evolved over centuries. If we look at the history of money, we observe that the changes have taken place because the former forms were inflexible for the demographics. Regardless of the type of money, whether it is commodity money (e.g. gold) or intangible IOU (e.g. banknotes), three criteria were always fulfilled: (1) store of value, (2) medium of exchange and (3) unit of account [1].

It is estimated that the cumulative market cap of cryptocurrencies went up from 0.21 million USD to 1.78 trillion USD between July-2010 and May-2021 [2]. This huge growth can be attributed to people’s positive opinion about cryptocurrencies being the next big financial innovation that would disrupt the financial system and the current form of money. To me it is a highly speculative idea. The fact that bitcoin and other similar cryptocurrencies are attractive to many young first-time investors, who believe that they can sell it for a higher price at a later point in time, demonstrates a sign of bubble.

  • Drop your iPhone into an empty glass to discover the power of acoustics.
  • Get the wrinkles out by hanging your clothes in the bathroom to let the shower steam remove the wrinkles.
  • Conditioner can be used as shaving foam or shoe polisher.
  • Always ask for two key cards.
  • Put away all the brochures, leaflets, and stand-up cards.
  • Bring a detergent (or use shampoo). You can use the sink or bathtub to wash your clothes. Soak them at least for 10 minutes before you begin to scrub. Do the soaking while taking shower. Rinse in shower. Roll wet clothes in a towel to dry. 
    • Timing: Do this trick in the afternoon, right after room cleaning.
    • Trick: Do in smaller batches, i.e. everyday. That way it's much easier to handle.
    • This is very fast. Compared to all the following: counting all your laundry, filling up the form, handing them to the reception, worrying about whether they managed/not, picking up after a long working day, taking the cleaned laundry out of the plastic bag etc...

When it comes to comparing things I am a big fan of ratios rather than looking at the absolute values. Here I did a quick analysis on a trendy topic to plan my next business trips before we all get travel restrictions:
