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?.
Both have a bond between each other, although that can affect ethereum and bitcoin differently at their respective stages, currently ethereum is looking good in the market and the trend is also very stable this month, and I don't think it's the right time to collect ethereum right now, considering that the purchase price this month is quite large for one ethereum, but if you want to make a purchase on ethereum, then wait for the time to go down first, then you collect as much as possible.
