Past performance is not an indication of future returns, please read the offer document carefully before investing - says every mutual fund offer document.
While the uptrend may not have ended yet, 33 to 2 to 20k does not imply 8k to 1 million. However, i agree with your advice. Keep calm and HODL.
Sure, no one can predict the future and nothing is guaranteed. I'm not saying this will for sure happen. Just my opinion that there's no reason it wouldn't.
