You don't need so much if you want to mine other crypto and trade it to BTC, which many people already do so here. A cheap CPU with a LGA 1150 mobo and 2-4 gigs of ram as well as a few RX 470s costs less than a S9 and it makes you more money. It's largely the reason why there's much less mining discussion about bitcoin these days.
I would say Bitcoin is way more stable and less volatile than other altcoins. Some altcoins like Monero dropped quite a bit in value a while ago, and if you were waiting a bit and maybe only selling every week, you might have lost a large amount of BTC after converting. ASICs also have fairly good resale price, not sure about CPUs.
Hi guys
To solve all your mining problem, I just discover a good faucet bot in cloud, you can get 1 BTC every week and you can start Collects 0.0005 BTC every 20 minutes with only 0,03 BTC.
this is the url go to the site and register for free and the buy some dedicated IP, start earning.
Good luck.
Nice try, but it isn't a mining thing and obviously a ponzi/scam that I highly doubt will pay out anyone, or force you to deposit a large amount before letting you "withdraw".
