Advice for a first time investor

Hey Reddit! I am new to crypto and I firmly believe that crypto has a lot of value, and is the future of currency. I have decided that I want to invest long term to secure a bright financial future for myself. I have done a bit of research, but because information is often contradictory I thought it might not be a bad idea to run my plans past you guys to get some more opinions.

I am 24 years old, and would like to buy myself a house by 40. I currently use binance and am planning to invest 500eu (on top of everything else I can spare) every single month. My plan is to invest 50% ETH, 30% BTC, 15% ADA, and 5% into a fotm shitcoin of choice.

Is there anything else I should consider before getting started? I already did a test run the past 6 months with 150eu, and managed to get 30% profits despite the recent drops. I am not an emotional person, and won't be falling for FOMO, hodl all the way.
