2009 was a historic year for bitcoin and was the first step in the emergence of the cryptocurrency ecosystem, no one thought that the enthusiasm of the public about bitcoin and cryptocurrency was so great that it could develop to this day.
If you look back, most people first got to know about bitcoin before knowing about altcoin, some even think that cryptocurrency is only bitcoin.
Sometimes this incident makes me smile a little, but that's how it is, bitcoin is the first coin that attracts people into the world of cryptocurrency.
