i've been using oneminers for both ASIC miner purchases and hosting for almost a year now and I can honestly say they are legit. I got my AL3 from them and decided to go w/ their hosting service to avoid the hassle of setting everything  up myself. Their customer support has been really responsive whenever i've had questions. They also provide a 7 yr warranty on their miners which adds some reassssurance. The hosting fees are competitive compared to other's i've looked at. You can check their website or check other users reviews or feedbacks for you to see.

Bitcoin's transparency ensures security but it can expose transaction history. To protect my privacy, i can use coinjoin to mix my transactions w others which makes it harder to trace. Using tor or a vpn to mask my IP address adds another layer of privacy. Achieving full privacy is challenging due to bitcoin's transaprent ledger, these tools help keep my financial activity more private and with future innovations, privacy could improve even more

Consider the following to retrieve bitcoin from the scammer
-cut off all contact immediately
-check the transaction where your bitcoin went
-report the scam to your local police or file a report (but do not expect that much help from them as you know the nature of bitcoin)
-if you used an exchange, tell them right away, they might help freeze the funds
-share your experience on bitcoin forums or other social media to alert others
-keep an eye on your wallet and accounts for any strange activity

Unfortunately, once bitcoin is sent, it is hard to get it back, so always be careful before sending any funds
