Are you gonna sell your coins?
No. No way. Let's just hope Ghash.IO stops doing this and possibly returns to 49%.
Guys, 50% is not a magical number. A pool at 49% is almost as dangerous as a pool at 51%.
The probability of a pool solving another 5 blocks in a row after solving the first one is
2.8% at 49% of total hashrate and
3.45% at 51% of total hashrate. Sure there is a difference, but you can't say a pool at 49% isn't something to worry about.
