Being new to mining one very important thing to understand that
all crypto coins are NOT the same and most have very different hardware requirements. In short, only 1 is Bitcoin
BTC. ALL others are altcoins and most of those are aka crapcoins because they are near worthless...
That said, this is the Bitcoin area and discussions are restricted to only Bitcoin. Period.
All questions & discussion for the
other coins belongs in the Altcoin areas.
As for mining equipment distributors,
only buy either direct from the manufacturers or only from their Authorized distributors that are listed on their site. Buying from anywhere else increases risk of being scammed and even more importantly, even if the gear is new it will NOT have a Factory supported warranty unless it bought from the mfgr or one of their Authorized Distributors.
Apologies as I just noticed that now, but I do want to do Bitcoin and was thinking of the Bitmain Antminer S19j Pro. I've seen that Whatsminer are better because of features and being bulletproof. I'm just trying to figure to buy the latest and greatest ASIC for Bitcoin or just buy used equipment to get started.
