Let go of all temptations and trade rationally, then whether Ethereum drops to 3000 or rises to 4200, the profits are about the same. Being overly bearish or chasing after prices is not right; looking at Bitcoin's strength, it's hard to break 100,000 without good news. Even with good news, there could be false breakouts to lure in buyers. After stopping out of my short position at 3470 yesterday, I became bullish, but didn't enter. I shorted again at 7 AM and made a decent profit.
The price has risen too quickly but has not yet had a sharp drop; the only possibility is that the depth is insufficient, making it easy to trigger a cascade of selling, which makes it difficult for the market makers to recover their costs for pumping the price.
Back to the market, most of the time going short leads to losses, while going long feels like bait; catching a spike to go long is like picking up money, but you never know when to pull out. I would rather miss out on a trend and wait for a familiar range to trade, or to short after a rise of several hundred points in the evening.
Once again, I remind you that driving the price up incurs costs, and these costs will eventually have to be recouped; the bubble that has been inflated will eventually burst.
