My goal is to join crypto currencies because I want to go into the world of business without capital as my side job. Even though it is a side job but I can grow on this job so my choice falls on the crypto currency business. I want a big profit from a business in crypto currency. Besides that, I joined crypto currency because I want to know blockchain technology more deeply so that later I want to create blockchain-based applications. After about 3 months I joined the crypto currency, I became more familiar with crypto currencies and I could feel the benefits of business in crypto currencies even though the results were not too high.
