My question is if it's still worth buying Asic's and start mining BTC in 2018.
If not mine BTC what other coin is it worth to mine nowadays?

Answer is No.
Unless you meet the following criteria
1. Can get Venture Capitalist to donate millions of dollars to you for a % of the bitcoin mined
Odds are you won't really make any money off of bitcoin mining, but will earn more keeping a % of the VC money as an administrator fee.
It is why you see companies offer cloud mining , they make more money off of the suckers that pay them to mine bitcoin,
than off of mining bitcoins.
PoW mining is for chumps and VCs that can throw away millions and not miss it.
