ETH mining (need fatwa)

Alsalam alaikum,

I am involved in a cryptocurrency platform that claims to provide a daily return of 2%. My recent earnings fluctuate daily, as shown below:

•	0.000185 ETH on 2024-11-05
•	0.000180 ETH on 2024-11-04 at 19:07
•	0.000179 ETH on 2024-11-04 at 13:07
•	0.000178 ETH on 2024-11-04 at 07:07
•	0.000178 ETH on 2024-11-04 at 01:07
•	0.000180 ETH on 2024-11-03 at 19:07

I would like to understand if this fluctuating income is halal, given that it’s marketed as a guaranteed return. Additionally, does this fixed return resemble riba (interest), and what specific factors should I examine to ensure my investment aligns with Sharia.
