Hi, would it be a good investment to buy US stocks, maybe around 1-2k per month using Gotrade and hold it for years 20-30 yrs?

I heard that for as low as 50 php we can invest in US stocks using gotrade. I dont have big money yet to invest, also not yet equipped to do so. I will probably do cost averaging, since I'm doing this just to start and learn more about it. What are your thoughts on this? I am a total beginner btw.

Btw, 1k - 2k per month is my spare money, so im thinking of buying US stocks instead of other stuff, and also considering PH stock, but I read not so good stuff, which one is better?

I would appreciate your insights!
