If I say I have a bit of compulsive order placement OCD and don't want to participate in the strategy of dollar-cost averaging into Ethereum below 1900, just to catch the bottom with full position.

In an extreme scenario, it means relying on Trump to negotiate with Iran and have the talks break down. Iran's stance is still relatively tough. If Trump launches a strike, gold will rise briefly, and Ethereum could be hit again with a 10% decline. Moreover, Trump wouldn't want to wipe out the other side; it's just to accumulate more bargaining chips, and ultimately, negotiations will resume.
But I think that's too difficult and overly idealistic. My current average price for Ethereum is still 1973. As long as it doesn't fall below 1750, I won't make a second dollar-cost averaging purchase.
Besides the split-position dollar-cost averaging, I also keep 50% of my funds in reserve. As mentioned in the subscription, to prepare for the US stock market, at least the folks on Wall Street won't actively enter the market until this hidden risk in the US stocks is addressed. Without large capital participation, there won't be a bull market.
