It is an issue worth considering that is for sure. One of those things people tend to over look or just forget about, especially if you not a miner.
Miners that dump and dont save most of their gains will kill themselves when 1 btc is worth 10K.
Well I hope that isn't the case. They will be very distraught and I'll feel bad for them when that time comes. It can be a hard choice for some who are deciding whether to hold or have the extra fiat in their hands.
