Banks in Germany started to allow people to buy and sell cryptocurrencies this January 2020. I think other countries will do the same soon, Japan might be another country with such services. In the beginning, someone has to start something so others can follow suit. What are the other countries where anyone legally can buy/sell cryptos at commercial centralized banks?
Aside from Japan & Switzerland where cryptocurrency movement is really strong and expanding, I am expecting that South Korea can be the next one for this trend. Though we are generally wary about banks getting into cryptocurrency I am still considering this as a good news because this can help this industry spread to as many people as possible. We have to admit that people are still trusting banks (even if we might refuse this fact) and so banks can therefore be of big help to convince more people to invest with cryptocurrencies. Banks are for profits and generally they want to deal with anything where they can be making money and where there is clearly a good demand. They are seeing it with cryptocurrency. Let's see and watch developments on this thing and whether this trend can be catching up fire and spread to many other countries as well.
Yes, banks are a good thing to be in the crypto industry, even when we know they are centralized entities, they are a good tool for achieving mass adoption. They might not be there all the time, once people realize the power of decentralization, they might stop using commercial banks!
The participation of banks in the provision of services for the exchange of cryptocurrency into ordinary currency is inevitable and will have only a positive side for cryptocurrency. The appearance of such an exchange in banks will simplify the purchase and sale of cryptocurrency and at the same time increase interest in it, because this will mean a serious attitude towards it from the state.
However, it should be noted that people will not stop using the services of state and commercial banks, since banks perform much more specific functions than cryptocurrency.
