Ethereum looks very Bullish now and likely to hit 4K in few days if Bitcoin remains Bullish. Once Ethereum's major upgrade occurs sometime in late 2021 or early 2022, one simulation estimates that the circulating supply of Ethereum could shrink by around 1.4% each year at current rates of fee burning. Is this the right time to collect eth and wait till upgrade happen?.
It is certain that the price of Ethereum will grow to new heights in the future and investing in Ethereum will bring good returns in the long run, but it is also possible that at any moment the cryptocurrency market dump will start when you will start investing in Ethereum, so I would not recommend invest now in Ethereum for the short term, but of course possible for the long term, but of course you have to decide for yourself when is the best for you to invest in Ethereum, and I think Ethereum will hit 4k$ soon, and most importantly, it's new a start for Ethereum, because I think next year Ethereum can grow to 2 times its price today.
