Are these any good for longterm?

Are these any good for longterm? I won't say i'm an avid investor as of now, but these two ETFs caught my eye and i've been invested in them for a couple of months. 1. Mirae Asset NYSE FANG+ ETF 2. Motilal Oswal NASDAQ 100 ETF Now, these ETFs usually are at their upper circuit, so getting a chance to get any of them at a discounted price is somewhat difficult. I try to buy the dip when it is a solid 3-4% in either of these ETFs. That gives me a solid margin to invest into either of them. We're looking at a solid >50% price increase in 1 year and I keep buying the dip, these profits could compound. What are y'all's opinions on this?
