Its ok if i lose. I dont mind since i am here to learn. Thats why i asked for advice. Btw thank you for all the answer

I entered in this world unlucky when it was at its peak. I already had like 0.16 btc back in the day when it was like 6000.
I bought since then 1 eth and 3 ltc and some xrp. In this d 3p i resist not panic selling and i did nothing apart from buy another eth and btc when it was at 600 and 12000. Then the dip continue and some of my friend sell to buy again when it was lower. Me since i was at a loss with alt coin i didnt do anything. Now i am still at loss with eth like 100 € and ltc like 200 € (coz i bought 3 at 290€) but its better than before. I am looking for advice. Did i behave ok? How to get better? Thanks
