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.
Then hold above, for the uptrend to continue, else we have to sell.
The fact that we stay far from the lows, and that very few people managed to buy down there is encouraging for now. Holding.
