ETF: Another wonderful investment tool

I've been a risk-adversed person when it comes to investing. Constantly investing into ETF has been a monthly ritual of mine and it has been pretty encouraging so far... For instance, I believe in the S&P 500 index however with limited fund, I can only opted those ETF which is smaller capped compared to $SPDR S&P 500 ETF (SPY.US)$  $Vanguard S&P 500 ETF (VOO.US)$ . The ETF I chose and have been DCA ever since was $SPDR Portfolio S&P 500 ETF (SPLG.US)$. The AUM is big enough for me and the expense ratio is still pretty low. Besides, to be exposed to the Chinese market, I have been consistently investing into $KraneShares CSI China Internet ETF (KWEB.US)$  which consists of various HUGE companies such as PDD, Baba and Tencent. Although I'm not making too much profit, but I still belive their time will come. If someone is pretty concerned about the Chinese government policies, this might not be one for me. As for leveraged or inverse ETF, I'm not a fan due to my lack my appetite for such volatility.
