I looked at Tesla when it was $20.00. Never pulled the trigger. 
I mined etn using fairhash and overclocked only to 475hz. My rate was almost always 276 Kh/s. I think it was at 150 MH at the time, didn't pay to close attention. I was doing around $28. a day. Now I'm experimenting with BCN from the UK. It's a pool that will share in the block if you find it. Already happened today. Both are low price coins so nothing earth shattering. thx for the info.

I bought around $15 and sold around $30 because I needed the money for rent. Literally like a WEEK later it jumped to $150. Live and learn.
I've since bought back in at various amounts at low points, but yeah, it's one of the few investing mistakes I'm kicking myself over.
