I have been Bitcoin swing trading for a year and I am still not profitable. I would like to be self-employed as an investor or trader after my IT education. Does trading really work in the long term to be profitable?
That depend about where do you live.
but the best advice I can give you is to try to limit your spending and entre the crypto market, buy anything that has a limited supply such as Bitcoin and XRP XMR BB, don't fall for the NFT.
how ever I also suggest trying your luck with creating a new ideas and bringing them to the life, build project and invest in things other that the Crypto market.
