What ETF’s have highest growth potential?

What is the most promising ETF in your humble opinion?
$The Technology Select Sector SPDR® Fund (XLK.US)$ , $Consumer Discretionary Select Sector SPDR Fund (XLY.US)$ , $Global X Lithium & Battery Tech ETF (LIT.US)$ , $Global X Robotics & Artificial Intelligence Thematic ETF (BOTZ.US)$ , & $ARK Fintech Innovation ETF (ARKF.US)$ are my main long-term holds bud I’m looking to branch out into less tech-heavy. Looking for ETF’s with max growth potential in this market.
XLY is my main squeeze (been holding shares for 7 years now). It’s done me very very well.
Then I found the tech side of the ETF world and in early 2016 I started heavily purchasing Vanguard and XLK(eventually leading me to ARKF & BOTZ) and these have 100% given me most the most gain.
Problem is I feel like I have all my eggs in one basket being in Tech. I’m looking for some other solid ETF’s y’all might be able to recommend.
Thanks!
