Timeline of Future Antminer X3-related events
April 5th 2018
Cryptonight-based coin IPBC will begin ASIC resistance tests.
April 6th 2018
Monero hard-fork will take place, Cryptonight ASICs will likely no longer be able to mine Monero efficiently.
Monero hashrate and difficulty will likely drop significantly, potentially allowing CPU/GPU Monero mining to be much more profitable.
April 16th 2018
Cryptonight-based coin GRAFT will become ASIC resistant.
April 30th 2018
MoneroV (XMV) hard-fork will take place. This is unrelated to the April 6th hard-fork, and many people have claimed this is a scam/has security risks. We cover this in an earlier guide.
May 2018
Cryptonight-based coin LeviarCoin will be "switching to Monero's code" (suggesting it will become ASIC resistant)
Unspecified date
Cryptonight-based Intense Coin will become ASIC resistant
