I am a beginner but learning fast. I firmly believe that cryptocurrencies are like artificial intelligence. They can not be and should not be avoided. They will certainly replace the coins and the paper money in a way or other in the near future. With more attention on security and on energy consumption, their growth will be accelerated. People should come out of the 'quick money' concept and should really start making use of their cryptocurrencies for their core transactions. Already large banks and corporates start to adhere to the blockchain technology which is used by cryptos. In some countries, retailers and wholesalers alike start to accept crypto transactions. Some governments start to study the possibilities of making way to cryptocurrencies. I consider all these as green signals.
