is there any plan to switch to cryptonight heavy before the individual asics arrive?
The algorithm will be changed to CryptoNight v7 (same of Monero), not CryptoNight Heavy (and it will be changed in the next weeks, before May).
The Masari network hashrate and dificulty start to rise exponential these days. Obviously asic miners jumping in to mine as much blocks before algoritm change. Dev need to hurry with the fork.
You do not need any fork. Nonsense. Nothing bad happens.
