We can take the long side here with low risk. Size it to fit 0.5 to 3% risk, if price drops against you by 1.9 euros.
Each coin you buy, your risk is 1.9 eur basically. For example, if your account is worth 10k Eur, you can buy a maximum of 157 ETH, which I'd reccomend you buy over a week or two, entering gradually. Split the purchase between a few days, amp up the size on drops, until you have a full position, if not, simply add the same amount gradually. A good time to buy is earlier in the day (5am in Shanghai), which usually aligns with the start of chinese activity in BTC, each day.
