I heard about it 2009/2010 and didn't buy it then because it just seemed like some scammy way to make money. When I learned more about its use and effects as a currency, I became interested and bought some, but its use as a legitimate currency just won't happen. In practice, it's just a scammy way to make money, always has been. The most useful thing about crypto was that you could convert it to USD for a profit, but the days of ez money have passed.
