1- Why buy hashing?

If you buy hashing, you can use it to develop on Bitcoin. You can also use it to mine Bitcoin. You can point hashing at any pool or self mine and capture Bitcoin from the source, Bitcoin Core. Freshly minted Bitcoin has never been circulated as it has never been on an exchange or in a wallet. Depending on your strategy for capturing Bitcoin, and the cost basis it is recorded at, miners have a few tools not afforded to buyers of BTC from exchanges and OTC. Buying hashing on Atomic is mining, without the cost and commitment of building and operating a mining facility.
