Everybody wishes they had gotten more serious earlier. I ran testnet. Nice toy, but the fan noise was bothering me. Fast forward to way too darn late. I knew a guy that did get serious, barely. I don’t know how many he had, but he traded 26,000 of the coins from his CPU for some of the first ASIC rigs. Tiny steps in the direction of something you believe in add up. It can be anything.
