I was an early adopter of crypto, when BTC and LTC were still the only stars; early enough that someone could do bitcoin mining with his own graphic card. I sold everything when BTC reached 150 EUR because I tough it's just a bubble. At that time, there were no legal applications of the blockchain, except some exchanges, and I saw no future in it. Now this is different, and I'm amazed with the huge number of applications that are built on the blockchain, and therefore I'm now here, on Steemit.
