I also sold a lot of ETH at $7 after buying at $6 and watching it go to $11 only to come back down to $7. At the time, the chart for ETH looked like along term downtrend and with no cap on the coin, it seemed it would just keep going down. The crypto market... is weird. Maybe some day coins like BitShares and STEEM will take off and people will tell stories about how they sold STEEM at $1 or $2 or how they sold BitShares at $0.25 or $0.40.
