Cloud vs. hardware crypto currency mining in 2018

I started with BCC, a small rig with 3 rx580 GPUs and hashflare 6 weeks ago.
$300 usd into Bitconnect
$1500 on my mining rig
$200 into hashflare

So after a bad start with bitconnect I am left with my Hashflare mining and mining rig

My strategy is to invest all earnings from the mining rig and reinvest my Hashflare earnings to compound my figures.
At the moment I have $660 in hashflare and $15 on the mining rig

I want and bitmain antminer but can not buy one as they are all sold out GRRRR
And expanding my RX580 rig is proving impossible as there are no cards
So I have bought 5 1050ti cards for another rig as any income is better than none but I expect the earning to be very low
