Luckily not many friends are asking us about miners in last couple weeks.
In short, we don't think it's yet the right time to do anything. If you never mined BTC or ETH, don't start now. If you never own any BTC/ETH, don't buy them. If you are mining, and someone can buy your rigs, and you feel uncertain or do not have a solid 3-4 year plan, now is a good time to sell your rigs.
