Hi everyone,

I would like an advice about investing in ETH mining right now, 1 month before the Ethereum Berlin Fork.

When ETH will be only with PoS, mining will become useless. Do you think it's a good time to invest in stuff to mine Ethereum now ?
My idea is even after the conversion to a PoS system, some coins will continue to work with PoW and ethash protocol like Ethereum Classic or Atheios.

I want to invest a bit in an ethash ASICS miner and switch on another altcoins when Ethereum will be full PoS.

I read a lot the last days but I really don't know if it's a good idea. Actually I'm 50/50 also that's why I post here my question. 

By the way I found this miner actually in presale and will be delivered in June 2021. Do you think it's a good idea or a really bad idea ? 2Gh/s seem huge!
I don't know if I can trust innosilicon and I don't know either if I will mine Ethereum one day due to the switch to PoS.

Sorry for my approximative English.

And thanks for the advices !
