Bitcoin mining was always my dream but back then I couldn't afford ASIC miners and I was mining altcoins with GPUs, which was nice but today it's not as profitable as it was years ago.
Finally, I have some money to buy a Bitcoin ASIC miner from Bitmain but I also have one fear for years. What if I receive a damaged ASIC miner? It takes months to receive them for China, it will take months to return them back to China and it will take some months to then receive them back again from China.
How do you risk buying ASIC miners from Bitmain? How often are their products damaged? Does it worth the risk to buy miners from them? How good is their support?
I feel your pain, I was in this same situation as you are some years ago and GPU mining become so obsolete since the day Ethereum abandoned proof of work, since that time I gave up on GPU mining but till date BTC mining is still very good, the only problem is BTC mining requires a more expensive miner called Asic miner.
I've never received a defeated Asic miners before, although all is not mine, but I do help people to order for any crypto miners available, the trick is ordering from the official asic miner companies, e.g Bitmain and others.
There are also few third party resellers too but you need to verify the source as this is one of the easiest way to get scammed. You won't have a problem buying from Bitmain, they will ship normally in a cared manner...
Everything you need to know about item safety measures is available on the official websites of all Asic Miners.
