I need bitcoin to go down to $2000 in order to repurchase. But maybe this is a dream)

See it in your dreams)

At the beginning of the year it was about $1000, now it is more than 7K

Haha, good one. BTC at $2000... It doubt if he ever touch 4000

But for PlayKey mining you will use only 1 GPU, what are you going to do with the other 5+ GPUs? You leave them in the mining rig. Also, the mining rig's CPU is too slow, you need more RAM and a bigger and faster harddisk. In practice you will have to buy a whole new high end rig to mine PlayKey and set it besides the coin mining rig. So in practice PlayKey cannot replace coin mining.

how much GPU computing power Playkey datacenter have? is there any information about datacenter anywhere?

2017 Q4: Access to exchanges: Cryptopia, Evercoin and Coinexchange.
thats a very good start, i like Cryptopia there have since last week a new user interface and also the support is super

Yes you will need a not so bad internet connection to play in good condition with playkey, but it’s the only requirement to enjoy all games on any laptop or computer no matter the power of your devices. Playkey will make gamers very happy !

This is good, but I with for better and biggest exchanges... They will hit or... ?

I prefer coinexchange and binance.
Especially binance, it has $144,054,671 volume and has added a few new coins and tokens.
And i think their requirements arent tighter than bitterx.

Many will want to use their laptops to play, so they could play anywhere they want, as long as there is a miner to provide them with the game near; internet connection is getting better and better, when this market booms, the internet connection will be good enough in the places there is more demand .
