I think this study by Coinbase is a very useful course. Thanks to this cryptocurrency base, I learn a lot of information about cryptocurrencies and it has visual support for the hearing impaired. I think this is a very good thing. The interface is easy and understandable, I think if you have just started the crypto business, use this course, but in some countries it makes you money, but thanks to this training, earning crypto money is great, you get information and you earn crypto money, but if there is another problem, it is a small number. education, I think this needs to be increased but one of the best courses, thank you to coinbase.
