Does anyone daytrade crypto?

Ive searched everywhere for people who invest in crypto but I only see poeple talking about unvesting long-term. I started with £150 2 months ago and now I have ~£7000 just daytrading SOL with no previous experience. Is this regular or is crypto not supposed to be daytraded? Im not sure if I just got extremely lucky, or I have some hidden smartness. But I feel like It shouldnt be this easy to trade. Up until I reached £4000 I mainly just put in all of my money into an order and pulled it out when it felt right. Since I havent learnt any strategies or techniques, I just Open Short when its near the 24hr high, and Open Long when its near the 24hr low, and I do it exclusively in SOL since it is the only future I've seen that changes price so quickly and makes trading more efficient. if anyone does daytrade, is this a sustainable technique to hold on to since it works? Also, is there anything else I need to know about crupto? because I have zero engagement with rge crypto community and this is my first time talking to anyone else about it, and I dont see news about what happens in the crypto world.

EDIT: Due to people saying that it isnt sustainable for the long term, I will report back in 2-4 weeks to update on how it is. I never expected to make so much so quickly when I first got into crypto, especially since im 15 and it just seemed like another fake "get rich quick" scheme
