You're kinda full of contradictions...
- says he played for 20 hours, then that he played for one year
- the game is too hard, play on hard difficulty
- ask for general advices, play modded
- is asked for traits, answer with ethics
...
It's going to be hard to help you without something more precise than "how do I expand my borders without spamming planets". We need to know more about your strategy and expansion patterns, especially in early game. Since you're playing a xenophobe empire you're supposed to expand fast through colonization in early game, then conquer/purge your neighbours. Your first true problem should be federations.
If you feel that normal is too easy and hard is too hard, there are also mods that add intermediate difficulty levels. Otherwise, I would advise you to play with other players (one of the great benefits from not polaying with a pirated version).
Also, mods like Ethics&Gov are more roleplay-oriented, while the hard difficulty needs the player to min-max. So either you have to use the mod to min max, or that's the reason why you're losing on hard.
I think these contradictions exist because the english language is not my native language and I didn't express my thoughts clear.
- I played on a pirated version a year ago for about 10 hours and haven't played since then. Then I bought Stellaris in steam and played for 20 hours
- Yes, the game is hard and I want to be better at the game. That's why I am asking for help
- So? I exactly need the general advices
- It's my fault, I didn't understand you. Currently I am using Industrious (+15% minerals), Decadent (Resource output without slaves -10%), Deviants (Ethic Divergence +15%), Multitasking (+5% Physical Research output, +5% Engineering output, +5 Social output), Born Warriors (+10% army morale, +10% army damage)
My strategy is that I want to colonize planets and get as much territory as I can (that's why I am asking what's the best way to do this) and conquer and enslave my neighbours, yes
Also I am asking for decent expansion patterns
What is the best starting weapon for this by the way? Should I spam corvettes? Is this still good in this version of the game?
I am not sure what do you mean? What is min-max? Didn't understand this sentence. P.S I can't play without Ethics&Gov because I love roleplay and I love the types of governments in this mod
