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?.
In my opinion EThereum is the best altcoin so there is no benchmark when we should buy Ethereum if we want to invest in the long term. unless we do live trades so we have to find a very precise time to be able to get higher profits. and my advice if you are a direct trader then you have to be more careful when buying ethereum because it can make you lose. and if you want a long term investment then the timing is not so important.
As we will invest for profit then we should think about the time when we will enter in the market. We can see after every few days, price of Ethereum gets up or down. At the time of bear market, we can go for buying Ethereum for long term holding.
