Went from 348 -> 300 in stamp so i sold 1/6 of my coins in first rebound at 330. I had 100% of all my wealth in coins (i don't have any loan). Lets see what happens next.
bought back at 324. can go lower, but it's not worth the risk. in next bigger dip i'll be ready again =)
EDIT. now its 311 =D
EDIT2. 300
