What kind of hardware do you plan to buy, I also want to start to build a rig.
I am not really new to the crypto sphere, I just mined with 3cards back in 2013, but not for Long only 3month or so
and now I want to do it again.


Currently I am searchin for some rx480, but could not find anything in Europe.
I have read and found some great Cluster PCI Expansion Cards where you can put 4 Cards into a cluster which only use 1PCI SLOT on
the Motherboard. Did anyone now something about it. With this solution it is possible to put 16Cards on one Board.

It couldnt be possible that there are only the same limits as in 2013, or am I wrong?

I think the strongest competitor now is Litecoin.

Segwit is fully activated since 2 weeks, the next big steps are the implementation of Ligthning, Mast - Smart Contracts.
If the BTC is gettin Segwit, these two can do instant cross change transactions without any exchange.

Then the Litecoin has the exact same adopation as BTC already has (because it can be used as a payment where you can pay with bitcoin) and you can use it to buy dalie stuff, because of its low transaction fees (1cent), and when LN is active the payment is available nearly instant.

So I dont know how nobody seems LTC is one the most valuable coins in 2020.

Just check it and read the Roadmap of 2017
