Trading (forex, crypto etc) as an individual while living in UK with T2 ICT visa

[saravanaag]

Hi There,

I read the below article, but still unclear as the last question was not answered and also its about 5+ years old one.
uk-tier-2-employer-sponsored-visas/can- ... 16067.html

My question is:
Can I invest my money in trading (forex, crypto) while I work for my sponsor in software projects (with T2 ICT long term visa). I am thinking to do it myself, and not as a business for others. My taxes are deducted during payroll by my sponsor, so anything I earn outside that should be self declared I assume. So, if I start making money with my investment, hope I am not going to be in trouble based on my visa?

Hope my question is clear.

Thanks,
Saravana
