Hi, could anyone please tell me how it will work… or is there any link to any kind of description for Dummies (most found are very technical) you could pass on which describe the ETH > EHT 2.0?
Assume that one has 10 ETH… will they be converted to ETH2?
Will there be ETH and EHT2 as two separate crypto?
If I believe in ETH / ETH2 – should one buy EHT now? Wait to the ETH2 is here or conversion (if there will be any)?
Confused… 
Thanks in advance for any kind of support in this topic!
Hey @Drabfab, hope you are good.
Now it could take a looooong topic to explain you the entire process xD.
But I could suggest your 2 resources to read and get more info on how ETH 2.0 will work and the entire process to migrate to it, this is still way to new and you have to follow closely those channels that are dedicated to follow ETH 2.0 process.
I do like Bankless enough to get indeep on Ethereum topics.
