I already heard about Blockchain technology in 2017. I started looking at Bitcoin growth for the first time. in 2018 i bought a pile of my first cryptocurrencies. Of course, I lost a lot of it. I am 23 years old and I envy everyone who learned about Blockchain possibilities earlier;)
Currently many people use this technology in their businesses. It develops in front of our eyes at an unimaginable pace and I like it 😁
