Taking a poll to see how many miners are coming back/upgrading in the next six months due to Ethereum DAG size and ProgPow change that should shift profitability very high for GPU mining.
I am expecting the following four events to create the perfect storm for GPU mining that will surpass the 2017/2018 mining profitability
- Ethereum DAG size going above 4GB in April thereby eliminating publicly sold ASICs (4GB memory) from network. Current estimate is 35% of hash
- BTC Halving in May should help stabilize prices
- ProgPow in July will remove any remaining ASICs
- By August if Corona virus is still disrupting China manufacturing, GPUs will be impossible to find as profitability soars for GPU mining
Bottom line is start preparing now for 2020 mining. In 2018, when mining profitability peaked, you could not find ANY GPUs to mine with.
