I recently got into cryptocurrency mining and decided it was time for a purchase of an ASIC miner. I actually knew some websites that are proven and tested by friends, but all of them are out of stock for the S19 Pro (I live in the USA), except some private offers which ask for unreasonable amounts of money.
Because everyone is trying to purchase gear and paying extra for anything that is available, ready to ship s19pro at 2400$ while bitmain is soldout for the August batch!? I know that you doubt it yourself for a while as it was a little too good to be true.
Their website isn't the greatest and all, but I couldn't find anything negative about them anywhere, so I decided to order.
Maybe you will say I am greedy and didn't do my research, I don't care.
Well, no point lecturing you and twisting the knife, take is simply as advice for the next time, come to the forum and ask about a company before doing the purchase, it might cause you to lose an opportunity investment but it might also prevent a loss.
Sorry for you loss, but honestly, don't buy mining rigs. GPUs are wayyy profitable and cheaper and you can buy them in any computer stores.
It takes about 5 Nvidia 3080 to match an S19pro at 5cents per kWh, good luck buying them for 500 each or about 8 3070s, again check the prices.
Also good luck with buying them at all. Not even mentioning that it is way easier for altcoins difficulty to grow and turning your earning to peanuts, with sha256 you need a ton of Asics for that, which as the OP experienced it's not on the market.
