As the global adoption of bitcoin/cryptocurrency keep expanding and more countries drafting a regulatory framework that allows crypto adoption as a legal tender some indices have been used to sort out the global crypto adoption rate, one of which is the number of Bitcoin ATM installations which the United 🇺🇸 happens to have the highest number of Bitcoin ATMs.
Comparing US and with other countries is totally worthless and not necessary.
But yes we need to really respect and support them for the massive contribution to the Bitcoins community.
Moreover more counties would have already adapted the Bitcoins ecosystem, but they are bounded to do so due to the decentralised nature of BTC .
Let’s wish that more and more countries supports Bitcoins in the near future, and we will be able to see more people showing interest in Bitcoins.
There are already good number of countries today who are seeing bitcoin as a promising currency and yet, it won't be easy to adopt it as a legal tender because most of the government are still making restrictions on bitcoin knowing it will be a threat to their own monetary currency. And indeed US has found to have lots of ATM bitcoin machines but it won't be enough to measure that its taking the lead in global adoption.
However, there are even countries today who has only less installed machines but you can see that the citizens have become user friendly and is really taking it as an edge towards other countries that are not even regulating crypto. Instead of US, it must be El Salvador i think which is more transparent to crypto and is more open to every opportunities that bitcoin may bring not just as a currency but maybe as a tool for investment too.
