Thank you a lot for your advice!! Regarding the website to buy the ASICs, is it better to buy it on Alibaba than the official website? (for example here: https://shop.bitmain.com/product/detail?pid=00020220215200429870z649US72061C). Couldn't be dangerous in Alibaba for scams? And also according on what I see on the official website, I think it's cheaper than Alibaba or other distribuirtors... What do you think? Thanks!
