I never expected japan to be so dedicated. When i heard them adopting bitcoin as a currency i was like ok fine we will see and little increase in price, but japan became a player it added bitcoin to more than 100k stores , made freakin multiple atm in the country and now it's opening the largest trading platform also. I wish it's neighbour china was also like this.
Japan was wise to jump on the crypto tech train. In the end it is one of few countries which actually invent tech, unlike China which only copies it.

Have it this way, many of the users may missed the early adoption train but that's not the case if you think country-wise.
Japan is the early adopter of bitcoin as a country. While China was banning its usage, Japan took a step forward and actually made it legal. So does Australia. As a result, these countries will benefit most from bitcoin.
Just like people who believed in bitcoin and endured anything for years.
