i bought a controller with 2x internal SATA and 2x USB3 , for two of my 3 pc's.  it was PCIe and it was dirt cheap. I used the internal extra SATA ports to put online some old disks i had lying around, and the external USB ports were used for 4TB intenso and seagate disks.  You want to verify that you have an extra PCIe slot before going that route..

I had 4x3TB WD Greens running in a home NAS for 2.5 years. One disk just died but he remaining 3 are running along just fine.
Does that make WD greens bad? Maybe not, but since then I have learnt my lesson and have switched to red NAS-disks instead. Hopefully they will perform better then the greens.

u get more burst buying on exchange with the same amount of money u use to buy HDD. And u get all the burst immediately buying from exchange. Mining the same amount would probably take at least 8 months (take note that block reward reduce every month at the rate of 5%) if difficulty were to remain at this level. If difficulty goes up again next month , u are looking at 1 year or more. If burst were to go up to 1000 sat next month, your profit is not as much as buying from the exchange because u will only get the same amount of burst that u can buy 8 months later. And using the profit u gain from buying burst from exchange , u can use the money to buy even more HDD if u really want to mine. Mining is only good when the price is up. Right now a better option is to buy from exchange, profit from raising price , use the profit to buy more HDD and mine later, Price right now is cheap compare to buying HDD and mine. When price goes to 300-400 , u can start thinking about mining if difficulty remains at this level.

If you have free SATA-Ports on your motherboard I suggest WD Green 3TB or 4TB drives. They are cheap, fast and quite reliable. External USB3.0 Drives are also fine, just don't pick Intenso (had lots of problems with them).

who stake? 

The market history is showing a lot of big sells and not a lot of buys. So, where do you get the idea that nobody is selling?

If the team distribute this coin again under new concept with afresh idea it will success

that would be @dano but I am pretty sure if you read it, it said it was a test.

Open the eyes of man, I lost money bought this shit. Flies down like a stone, you can not see the bottom. Dev gives recipes for drinks, for I had lost btc few bottles real Malibu

I think there is something wrong. Option two, or someone bought cheap coins and preparing hdd for very rapid growth of diff, and hence growth price. Or someone hacked  the network, the network grow almost twice in one day, it's something very strange.

Who mine on pool v1? What you say about two last day?

Yeah, could you find an owner of that fucking bot?

yes, definitely.
