Would it be permissible to ask a bit of donation for something

Assalamalykum.

I wanted to know is it permissible for me to ask for money for something that I need urgently for my studies.

My phone is not working as a result of being old and while I’m earning money to purchase myself.

My university has started giving me lot of work and I’m finding it hard to focus on study as I’m focused on earning money.

Is it permissible for me to ask money on any fundraising website in cryptocurrency ($20-30) so It can help me.

The problem is I always look for platforms where I can earn money and what ends up happening is I then come here and ask if its compliant or not because of many concepts like DEFI NFTS etc which are dubious to me at the same time

I don’t want to earn haram money but at the same time i also want to focus on studies(Computer science course).

Is this permissible, if yes
Can anyone can help me?
